René Kliment Posted January 20, 2018 Share Posted January 20, 2018 Hello everyone. This happens on my OrangePi after a couple of hours of running. I don't think this happened before installing the kernel 4.14. I haven't changed my power supply, which should be working well - custom DC/DC converter connected to GPIO pins. Is anyone else experiencing this? Anything I can do?

Happens with both idle and busy Pi. I've been trying to rsync+ssh from a remote to an USB connected HDD. The HDD has its own power. Also, the Pi has a heat sink, so no overheating either.

René Kliment Posted February 7, 2018 Author Share Posted February 7, 2018 The only workaround I have been able to come up so far is capping the CPU frequency pretty low - 480 MHz max - bigger wouldn't work for me and would always stall after a couple of hours. I've been able to run it for 2 days straight now with cpufreq-set --max 500Mhz 0 Quote Link to comment Share on other sites More sharing options...

Igor Posted February 10, 2018 Share Posted February 10, 2018 It seems that latest nightly build (4.14.18-sunxi/4.14.18-sunxi64) also works just fine. I am currently heavily stressing out: - Cubietruck - Orange Prime - Orange 2E Uptime: 15 hours 56 minutes 50 seconds If they are still up by the end of the day, I'll push kernel to the repository. 0 Quote Link to comment Share on other sites More sharing options...

I don't have a log unfortunately, but I believe it would be same as yours. I see there is kernel 4.17.6 available, testing it now to see if it is fixed or not. Maybe a patch that fixed this before got left out?@Igor 0 Quote Link to comment Share on other sites More sharing options...

It's also possible that some boards are much lower quality than expected with our already conservative settings. It's not just kernel, but also u-boot.

It's not just kernel, but also u-boot. Both are changed now. Board quality is definitely a factor. However, it worked fine for me in early 4.14 kernels, then got broken, then got fixed again and now it's broken again so it seems like a kernel and/or uboot issue. Let's hope it will magically fix itself again :-O I can confirm that it froze with 4.17.6. I've upgraded to 4.17.8 and connected the serial console to catch the dmesg output when it freezes again. 0 Quote Link to comment Share on other sites More sharing options...
Links2004 Posted July 21, 2018 Share Posted July 21, 2018 Hi, can confirm that this still is a big Issue, (running a Orange PI PC) since I updatet from 4.14.18-sunxi to 4.17.7-sunxi the system is in a dead state very. before the update the system where running for month stable. Interesting is that the first notable think is that ssh stops working (aktive session is dead and new session gets a timeout), ping and the home automation stuff running there will run ~1hour more and then the system is dead complete. some log which may or may not helps here: Spoiler Jul 21 17:00:01 localhost CRON[2647]: (CRON) info (No MTA installed, discarding output) Jul 21 17:05:01 localhost CRON[2719]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1) Jul 21 17:09:16 localhost systemd[1]: Started Session c5 of user root.

AndrewT Posted August 13, 2018 Share Posted August 13, 2018 Same problem here: Banana PI M1 - ARMBIAN 5.38 stable Debian GNU/Linux 9 (stretch) 4.14.18-sunxi It makes a daily reboot and runs for a couple of days, maybe 3 to 5. Then the system partial stops to work. SSH login works, but my cronjobs don't run. And it seems that the system is just using one of the two cpu cores. When I try to restart the system with "reboot", it doesn't come up again. I have to use the reset-button.

René Kliment Posted August 24, 2018 Author Share Posted August 24, 2018 I've been running 4.17.14-sunxi for 4 days straight now and it's crunching two `openssl speed` in a loop at 1200 MHz. So far so good. Maybe this patch has something to do with it? https://github.com/armbian/build/commit/3326ccc11648e5ff482102ec401b22cc795006ae I don't have time to compare with and without, but I'm super glad it works now :-) 0 Quote Link to comment Share on other sites More sharing options...

I was able to get the machine stable by setting cpufreq to a fixed frequency. It does not matter if I set it to low or high so mine's now stable running at 1.37Ghz for days. Did you lock yours at 1200Mhz or was it just never idle ? (Is it still stable for you?) [1] https://github.com/megous/linux/ 0 Quote Link to comment Share on other sites More sharing options...

All my H3 (also H2+) devices suffer from the issue as described. Even with newest kernel. So, after reading I decided to test stability with "constant cpu frequency". EDIT: I've done it by: [root@PKTEST ~]# cat /etc/default/cpufrequtils # WARNING: this file will be replaced on board support package (linux-root-...) upgrade ENABLE=true MIN_SPEED=408000 MAX_SPEED=1296000 #GOVERNOR=ondemand GOVERNOR=performance [root@PKTEST ~]# Question: would it be possible not to overwrite cpufrequtils file once support package is installed/upgraded? 0 Quote Link to comment Share on other sites More sharing options...
piknew Posted October 21, 2018 Share Posted October 21, 2018 Could you please take a look here: Considering that when running on performance mode - system seems to be stable but once switched to "ondemand" - unstable. May the "mismatch" be the root cause here? 0 Quote Link to comment Share on other sites More sharing options...

On 10/10/2018 at 7:14 PM, piknew said: Question: would it be possible not to overwrite cpufrequtils file once support package is installed/upgraded? This part is due to rework but since developers count is low, it takes a lot of time to get there. 0 Quote Link to comment Share on other sites More sharing options...
piknew Posted October 22, 2018 Share Posted October 22, 2018 For now I have modified cpufrequtils as following for my three boards (orangepipc, orangepiplus 2 GB, orangepiplus2e): [root@PKBACKUP ~]# cat /etc/default/cpufrequtils # WARNING: this file will be replaced on board support package (linux-root-...) upgrade ENABLE=true MIN_SPEED=480000 MAX_SPEED=1296000 GOVERNOR=ondemand #GOVERNOR=performance For orangepizero as following: [root@PKOTHER ~]# cat /etc/default/cpufrequtils # WARNING: this file will be replaced on board support package (linux-root-...) upgrade ENABLE=true MIN_SPEED=240000 MAX_SPEED=1200000 GOVERNOR=ondemand #GOVERNOR=performance Only orangepiplus2e is somehow loaded. With my own backup software, which is run twice a day - but in the past it was enough to freeze the board after a few days. I will update if the change helped or not. Question: I have noticed that orangepizero is using lower "MAX" settings. I understand as this device had an issue with overheating. How about other platforms, why lowest frequency settings is 480 MHz, not 240 MHz (which is also supported by H3)? Some results for my platforms (please note that 816 MHz is common lowest choice for H3): orangepiplu2e: [root@PKBACKUP ~]# armbianmonitor -m Stop monitoring using [ctrl]-[c] Time CPU load %cpu %sys %usr %nice %io %irq CPU C.St. 16:36:53: 1296MHz 0.00 6% 1% 2% 0% 1% 0% 42.5°C 0/9 16:36:58: 816MHz 0.00 0% 0% 0% 0% 0% 0% 43.0°C 0/9 16:37:03: 816MHz 0.00 0% 0% 0% 0% 0% 0% 42.8°C 0/9 16:37:08: 816MHz 0.00 0% 0% 0% 0% 0% 0% 42.8°C 0/9 16:37:14: 816MHz 0.00 0% 0% 0% 0% 0% 0% 40.2°C 0/9 16:37:19: 816MHz 0.00 0% 0% 0% 0% 0% 0% 43.4°C 0/9 16:37:24: 816MHz 0.00 0% 0% 0% 0% 0% 0% 41.7°C 0/9 16:37:29: 816MHz 0.00 0% 0% 0% 0% 0% 0% 41.6°C 0/9 16:37:34: 816MHz 0.00 0% 0% 0% 0% 0% 0% 42.5°C 0/9^C orangepiplus: [root@PKHELPER ~]# armbianmonitor -m Stop monitoring using [ctrl]-[c] Time CPU load %cpu %sys %usr %nice %io %irq CPU C.St. 16:39:34: 816MHz 0.13 0% 0% 0% 0% 0% 0% 44.2°C 0/9 16:39:39: 1296MHz 0.18 0% 0% 0% 0% 0% 0% 43.8°C 0/9 16:39:44: 816MHz 0.17 0% 0% 0% 0% 0% 0% 43.9°C 0/9 16:39:49: 1296MHz 0.16 0% 0% 0% 0% 0% 0% 43.7°C 0/9 16:39:54: 816MHz 0.14 0% 0% 0% 0% 0% 0% 44.0°C 0/9 16:39:59: 1296MHz 0.13 0% 0% 0% 0% 0% 0% 44.3°C 0/9 16:40:04: 816MHz 0.12 0% 0% 0% 0% 0% 0% 44.3°C 0/9 16:40:09: 816MHz 0.11 0% 0% 0% 0% 0% 0% 43.7°C 0/9 16:40:15: 816MHz 0.10 0% 0% 0% 0% 0% 0% 43.1°C 0/9 16:40:20: 816MHz 0.09 0% 0% 0% 0% 0% 0% 43.7°C 0/9^C orangepipc: [root@PKTEST ~]# armbianmonitor -m Stop monitoring using [ctrl]-[c] Time CPU load %cpu %sys %usr %nice %io %irq CPU C.St. 16:41:11: 1296MHz 0.07 0% 0% 0% 0% 0% 0% 35.7°C 0/9 16:41:16: 816MHz 0.06 0% 0% 0% 0% 0% 0% 36.7°C 0/9 16:41:21: 816MHz 0.06 0% 0% 0% 0% 0% 0% 36.8°C 0/9 16:41:26: 816MHz 0.05 0% 0% 0% 0% 0% 0% 35.7°C 0/9 16:41:31: 816MHz 0.05 0% 0% 0% 0% 0% 0% 35.9°C 0/9 16:41:37: 816MHz 0.04 0% 0% 0% 0% 0% 0% 36.5°C 0/9 16:41:42: 816MHz 0.04 0% 0% 0% 0% 0% 0% 35.8°C 0/9 16:41:47: 816MHz 0.04 0% 0% 0% 0% 0% 0% 36.4°C 0/9 16:41:52: 816MHz 0.03 0% 0% 0% 0% 0% 0% 36.2°C 0/9^C orangepizero: [root@PKOTHER ~]# armbianmonitor -m Stop monitoring using [ctrl]-[c] Time CPU load %cpu %sys %usr %nice %io %irq CPU C.St. 16:42:33: 1200MHz 0.00 0% 0% 0% 0% 0% 0% 43.0°C 0/8 16:42:38: 648MHz 0.00 0% 0% 0% 0% 0% 0% 43.1°C 0/8 16:42:43: 648MHz 0.00 0% 0% 0% 0% 0% 0% 43.1°C 0/8 16:42:48: 648MHz 0.00 0% 0% 0% 0% 0% 0% 42.6°C 0/8 16:42:54: 648MHz 0.08 0% 0% 0% 0% 0% 0% 42.5°C 0/8 16:42:59: 648MHz 0.07 0% 0% 0% 0% 0% 0% 43.6°C 0/8 16:43:04: 648MHz 0.06 0% 0% 0% 0% 0% 0% 43.0°C 0/8 16:43:09: 648MHz 0.06 0% 0% 0% 0% 0% 0% 42.6°C 0/8^C 0 Quote Link to comment Share on other sites More sharing options...
rufik Posted October 22, 2018 Share Posted October 22, 2018 why lowest frequency settings is 480 MHz, not 240 MHz (which is also supported by H3)?Because everything lower than 480 trashes SD card performance, as@tkaiser wrote a few times. 0 Quote Link to comment Share on other sites More sharing options...

This GPS C program just reads GPS at /dev/ttyS2 at 9600bd I have made a lot of work with the script and GPS-program having no luck but learned a lot. Processor speed 480-1102MHz. I took a photo of the frozen screen and made Google find this forum. Here is the part of my script, which gets data from the GPS-program: timeout 3 /home/bin/i2cLCD/gps >$TMPFILE & pid=$! echo "PID: $pid" wait $pid read uline < $TMPFILE 0 Quote Link to comment Share on other sites More sharing options...
