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
