Update: after issue was unsolved on both boards, i moved usb disks from smb server to tinkerboards, mounted storage and i'm using usb storage without issues. So, issue was 30% caused by power supply and 70% due heavy smb usage which caused threads hangs as smb server disconnected clients. Now, i have 3 boards with usb powered 2.5" hdd (all powered via board micro usb connector), they are stable.

i'm trying minerd, but board seems stable as voltages. Maybe there is something on software level...

i used stress-ng + memtester. however, after previous reply, armbian running board hanged, so i'm giving up.

Hi all, as you told me before, it's likely an 5V power issue; i was stupid i didn't double checked with another different cable-power supply combination. At the end, i changed power supply with an SBS 7A 4 port usb charger SBS model TTTRAV5USB7A and i replaced 1 micro USB cable, now both boards are working fine from yesterday morning (now, they are online from 30 hours). So, i had 2 power supply which weren't capable to deliver enought current and 1 usb cable with too much resistance despite is 30cm long. My test were: Raspberry pi PSU, crash on both boards Ikea battery with 30cm cable, crash on both boards Onite battery with 30 and 60cm cable, crash on both boards. PC capable delivering 2A, 30cm cable, crash on both boards. Yesterday, before buying new power supply, i tried ikea battery with 60cm usb cable, board was stable. Then i replaced raspberry pi psu and 30cm usb cable and they seems to work fine. So, thank you all for time you spent on me, next time i'll triple check power supply issue before posting.

Yes, i'm using two different distribution in two different boards, i exchanged microsd card to check if one board is more stable than other, but they seems to be twins (compare against other Linux version may be useful). Armbian version, now is the latest (as i told on Sunday), base image, desktop disabled, only zoneminder + apache2 installed (sql server is on other pc); i use smb shares to store images. Cameras are IP cameras, not USB, there is nothing attached on USB ports. However, i replaced power supply, boards seems to be stable, but i'm still testing both (power over micro usb). Yes, zoneminder uses FFmpeg, but jpg encoding is still an cpu task. My doubt is about why board hanged after an progressive slow down in performances at normal cpu speed? If was only an power issue, board would crash or reboot without slowing.

Update 2: i'm using both official Asus image and Armbian_5.33.171008_Tinkerboard_Ubuntu_xenial_dev_4.14.0-rc3_desktop.img nightly build. First image seems stable with one camera @ 20fps (powered by Raspberry pi PSU, i won't add any other camera due hanging issue) Second image seems stable with two cameras @ 10 fps each (powered by ikea SOLBANA), last image hanged after 10 - 20 minutes, this is still running after 1 hour. I hope i can make this topic solved (due something been updated), but stay tuned. Update3: issue is not solved.

update: casually, i found this error on official thinkerboard debian image: Message from syslogd@linaro-alip at Oct 7 13:37:07 ... kernel:[ 1440.791144] Kernel panic - not syncing: hung_task: blocked tasks

Standard armbian OS upgraded until 2 weeks ago kernel/patches, zoneminder, apache and mysql. Everything you need is posted above, in firsts comments (with results). However, raspberry psu is cold, it's rated 2.5A peak and 2A continuous usage. Measured amperage says 1.5A peak current, so it's a lot lower than continuous permitted current, i also added an capacitor in case of voltage sag, but it seems to do nothing. tkaiser, thank you, it was one of think i tried. Now, i'm testing a new configuration, then i'll try with armbian image.

As told before, raspberry pi branded psu, no usb devices connected. I tried also an ikea powerbank and a no-name powerbank, which proved to support 2A. I ruled out usb connector issue, because i used GPIO in board without differences. I'm thinking it's something about RAM and SWAP use: i can replicate this issue running memtester, which left some 50MB of free ram, i try to open it apache2 server and... BAM, board hanged! I measured amperage with stress-ng -c 4 (quad core cpu)

Hi all, new tinkerboard, same issues.

i've just submitted an assistance request to Asus. update: i'm running stress-ng to stress-test cpu. i'm also running memtester for ram. update 1: during test i tried access internal apache server, this partially hanged tinkerboard (but memtest was running fine) then, after 5 minutes, it resumed from hang. now, i'm suspecting something on swap file disabled. update2: enabled swap, testing for system stability. System unstable as usual; on htop, kernel threads were at 100% update3: i measured amperage, at full cpu load is 1.5A (rounded up). Now, i've contacted seller for an rma.

Tried also with asus debian image, same issues. Maybe hardware issue?

@Tido, hot removing/plugging sd card is the best way to get corrupted filesystem. with another pc, check filesystem.

I was thinking about thermal protection, but measured temperatures (and with not-so-bad infrared thermometer) are on 50-60°C in the hottest part of board. Now, i run test on forced cooled case, same results, so temperature maybe not an cause of this behaviour. I noticed, prior to system crash, system slow down to hell (and declared cpu frequency doesn't change at all), maybe something about massive interrupts or process queue issues?

update: i noticed system bash become unresponsive prior hangs. df -h command wait something forever service command do same thing system load jump to 8.50 apache server hangs. maybe some process which is out of control? more then i wait, more processes go to "uninterruptible sleep" "D" status on htop. io bottleneck? last hang: top: top - 11:26:11 up 16 min, 4 users, load average: 3.87, 3.50, 2.31

yesterday i tried, hanged after 1 hour. I tried with different power supplies (2 of Raspberry pi 2.5A power supplies and one battery bank). Now, i'm trying an ikea battery bank, which have unstable voltage output (on GPIO vcc pins float between 4.7 and 4.8V) after 15 minutes hanged. I don't have any good powered usb hub. I'm trying resizing ram buffer, etc with 3 cameras, hangs after 5 minutes. when hanged, it had 3 ssh sessions opened: armbianmonitor -m 10:25:01: 1800MHz 4.63 38% 3% 25% 0% 8% 0% 58.2°C root@tinkerboard:~# htop 1 [||||||||||||||||||||| 30.7%] Tasks: 69, 72 thr; 2 running 2 [||||||||||||||||||||||||||||||||| 50.0%] Load average: 4.63 2.79 1.24 3 [|||||||||||||||||||||||||||||||||||||||||||||||||||||||||32.2%] Uptime: 00:08:11 4 [||||||||||||||||||||||||||||||||| 49.3%] Mem[||||||||||||||||||||||||||||||||||||||||||||||||||||943M/1.96G] Swp[ 0K/128M] PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command 3325 www-data 20 0 342M 193M 185M R 43.1 9.7 0:40.68 /usr/bin/zma -m 4 1769 www-data 20 0 423M 233M 211M S 27.9 11.6 2:07.05 /usr/bin/zmc -m 8 3116 www-data 20 0 404M 212M 189M S 27.2 10.6 1:15.95 /usr/bin/zmc -m 2 3270 www-data 20 0 341M 190M 184M S 25.2 9.5 0:23.68 /usr/bin/zma -m 2 2754 www-data 20 0 404M 212M 189M S 24.5 10.6 1:10.63 /usr/bin/zmc -m 4 2780 www-data 20 0 404M 212M 189M S 6.0 10.6 0:14.09 zmc 3154 www-data 20 0 404M 212M 189M S 5.3 10.6 0:15.44 zmc 1921 www-data 20 0 423M 233M 211M S 4.6 11.6 0:21.19 zmc 3151 www-data 20 0 404M 212M 189M S 4.0 10.6 0:10.47 zmc 3155 www-data 20 0 404M 212M 189M S 4.0 10.6 0:10.57 zmc 3152 www-data 20 0 404M 212M 189M S 4.0 10.6 0:10.43 zmc 3153 www-data 20 0 404M 212M 189M S 4.0 10.6 0:10.46 zmc 1922 www-data 20 0 423M 233M 211M S 4.0 11.6 0:16.51 zmc 1925 www-data 20 0 423M 233M 211M S 3.3 11.6 0:15.05 zmc 1923 www-data 20 0 423M 233M 211M S 3.3 11.6 0:14.84 zmc 1924 www-data 20 0 423M 233M 211M S 2.7 11.6 0:14.85 zmc 2782 www-data 20 0 404M 212M 189M S 2.7 10.6 0:07.76 zmc F1Help F2Setup F3SearchF4FilterF5Tree F6SortByF7Nice -F8Nice +F9Kill F10Quit top: root@tinkerboard:~# iostat Linux 4.13.0-rockchip (tinkerboard) 09/20/2017 _armv7l_ (4 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 24.30 0.20 4.56 4.15 0.00 66.78 Device: tps kB_read/s kB_wrtn/s kB_read kB_wrtn mmcblk0 18.83 889.21 248.86 295145 82600 root@tinkerboard:~# iotop Could not run iotop as some of the requirements are not met: - Linux >= 2.6.20 with - I/O accounting support (CONFIG_TASKSTATS, CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING) root@tinkerboard:~# top top - 10:25:04 up 8 min, 3 users, load average: 4.63, 2.79, 1.24 Tasks: 153 total, 2 running, 151 sleeping, 0 stopped, 0 zombie %Cpu(s): 11.2 us, 2.5 sy, 0.0 ni, 77.9 id, 8.1 wa, 0.0 hi, 0.4 si, 0.0 st KiB Mem : 2054344 total, 56352 free, 371780 used, 1626212 buff/cache KiB Swap: 131068 total, 131068 free, 0 used. 1010556 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3325 www-data 20 0 364548 211804 189904 S 29.6 10.3 0:40.95 zma 31 root 20 0 0 0 0 R 24.3 0.0 0:00.73 khungtaskd 3116 www-data 20 0 413720 217104 193860 S 20.9 10.6 1:16.19 zmc 1769 www-data 20 0 433784 238692 216416 S 20.3 11.6 2:07.26 zmc 3270 www-data 20 0 349228 194748 189088 D 18.6 9.5 0:23.88 zma 2754 www-data 20 0 414112 217932 193900 S 16.3 10.6 1:10.76 zmc 1017 root 20 0 0 0 0 S 0.7 0.0 0:02.19 cifsd 8 root 20 0 0 0 0 S 0.3 0.0 0:00.89 rcu_preempt 25 root 20 0 0 0 0 S 0.3 0.0 0:00.17 ksoftirqd/3 2679 root 20 0 4912 2612 1984 S 0.3 0.1 0:03.96 htop 3687 root 20 0 0 0 0 S 0.3 0.0 0:00.17 kworker/0:2 4054 root 20 0 0 0 0 S 0.3 0.0 0:00.13 kworker/3:0 4298 root 20 0 6572 2656 2216 R 0.3 0.1 0:00.03 top 1 root 20 0 22808 3724 2532 S 0.0 0.2 0:02.89 systemd

Update: using only one camera is STABLE. When i start recording on 2+ cameras, hangs. Today i'll try reduce shm size and, eventually, using an fan over tinkerboard.

Ok, thank you all, i'll try as soon as possible. update: now, i'm running ARMBIAN 5.32.170920 nightly Ubuntu 16.04.3 LTS 4.13.0-rockchip reboot is fixed. update2: now, it seems more stable, but after 1 hour, it hangs again (red led stays on, sometimes also green, yellow stop to pulse). I tried updating board firmware, i'll let you know about results...

Hi, as usual i thank you for support. I mapped 1.25GB of ram as /dev/shm for data shares, swap is 128MB, 0% used (because swappiness is 0) First, i was thinking about thermal issues, but it doesn't seems to be the problem (board hangs also where placed over an thermal pad with generous heatsink). Last armbianmonitor -m print (before hanging) was: 11.95 of load is very strange as normal is near 2. I noticed board hangs faster as cpu workload increase. update: changed sd card with a new Samsung MB-MG16EA/EU, nothing solved. I'm writing an new image to sd card, maybe system corrupted? update2: shutdown -r now doesn't reboot. update3: all configured as original, testing new installation (img without desktop environment) for log analysis: http://sprunge.us/FJib

Update: i upgraded kernel getting latest package from https://apt.armbian.com/pool/main/l/linux-4.12.0-rockchip/ and running dpkg -i *.deb now, i'll let this run for a while, meanwhile i'm going to buy a new micro sd card, i'll test it in case of hangs. (i'll do tomorrow) p.s. i noticed shutdown -r now command doesn't reboot, but seems to shutdown without reboot option, may be an help for find the solution on my issue? updated kernel, after 30 minutes, it freezes (again).

Thank you very much for support! Tomorrow i'll cut the micro usb cable to power via GPIO (with misc filter capacitors). Now, i'm searching about upgrade Armbian kernel. (10.10 am update) i cut micro usb connector, i'm using GPIO connector for power. Voltage is between 5.30V and 5.29V (10.45 am update) no differences, board continue to hang...

Ok, thank you! Now it's quite late, but i'm going to monitor voltage on 5Vcc GPIO pins. I'm going also to upgrade kernel version. However, if is power supply, why every power supply thinkerboard after a while? I noticed, setting lower frequency limit in cpu governor that setting more than 600MHz make this board more stable... (edit 1): voltage on vcc pin on gpio is 5.11-5.14v under load at 1.5GHz, after 2 minutes, it stabilizes on 5.2V and then, drop to 5.17 when board hangs.

Good morning all! I started with sbc when first Raspberry pi appeared (256MB of ram!), now i bought an Asus Thinkerboard to use with Zoneminder as server in an low power cluster video-surveillance system (at my home). OS: Armbian 5.30 Ubuntu Xenial next 4.11.4 from ufficial torrent. The board works just fine, except frequent hangs after 5-10 minutes of use. I tried with different power supplies on micro usb port (2 of raspberry pi, 2.5A@5.1V and an external battery phone charger, i have also connected an 1x1000µF capacitor across gpio 5vcc terminals and ground); measured voltage seems to be ok. The system doesn't have any usb device attacked and system boots into terminal mode. Cpu governor is set to stay between 1.1GHz and 1.5GHz, temperature is 50-70°C and thermal throttling engage rarely (i have also changed thermal paste with an better quality). I tried checking SD and Power supply, but i don't have any clue about this issue. htop is saying about 50% cpu, 2.x system load After some minutes, system simply stop to respond: lan goes down and, when logged into local terminal session, i can only press enter (everything else won't work). Sd activity (green led, i suppose) stay on, yellow led goes off (normally, it blinks). Does anyone have any idea about this issue? Thanks!
