How to do a full hardware test?

[dieKatze88 5]

I backed this early, and I have had nothing but stability problems since I built the thing. Sometimes my machine runs for as few as 6 minutes before crashing, and helpfully, it keeps clearing the systemd journal every time it starts up so I can't even see what happened just before it crashed. It crashes running OMV and Syncthing with high load, it crashes doing absolutely nothing but watching the systemd journal. It crashes doing nothing at all.

When it crashes, it corrupts my files, and often the OMV Database requiring me to CONSTANTLY reset the GUI password for OMV, and then find that half of OMV isn't working. It does this on both uSD cards and on the inbuilt MMC.

I'm nearing my end with this thing, how can I do a full hardware test on it in a way that will say "Yes this is working as expected" or "No this is defective."

Providing logs with 

armbianmonitor -u

 helps with troubleshooting and significantly raises chances that issue gets addressed.

[gprovost 156]

@dieKatze88 Which kernel version are you running ? There has been significant stability improvement with latest one (version 5.10.21) ?

 

Any chance you can have the serial console opened in hope to catch something when it crashes ?

[dieKatze88 5]

I have disabled zram, as it was suggested by someone on Reddit.

 

I am now running the latest kernel, but absolutely no kernel in my history of this thing has been stable.

I got the following serial console the last time it crashed (But could not edit my post due to limits):

Sorry didn't see that you needed a like in order to remove the 1 msg / day limitation. Still need to wait 12 hours for it to be lifted.

 

Actually I'm wondering if the U-boot you are using on eMMC is the correct one.

 

Could you post here the early stage boot log of your unit ? You will need serial console connected before you switch on the board.

[dieKatze88 5]

It crashed again last night. I Have two blocks for you. Both of the Kernel Panics posted here have been from a SD boot with the emmc wiped.

[gprovost 156]

Ok that's the correct U-Boot.

 

Hmmm seems to be still stability issue related to the scheduler / DFS.

 

Have you tried to use Performance Schedule ?

 

armbian-config > System > CPU

 

Minimum CPU speed = 1200000

Maximum CPU speed = 1200000

CPU governor = performance

 

[dieKatze88 5]

I have set those settings tonight and we'll see if it crashes by morning.

[dieKatze88 5]

OK After 13 hours we're still up (Even with a light load of sending massive pings on the 2.5g interface to my desktop)

I'm going to give it one more day before I call it good and try reinstalling to the internal flash again.

[dieKatze88 5]

I've gone ahead and reinstalled to the internal flash, setup with a more minimal system (Not using OMV) and am monitoring it for failures. Any reason why some units are only stable at 1.2ghz?

[gprovost 156]

@dieKatze88 You can setup the highest frequency and the outcome will be most likely the same. The issue is not the frequency speed, is the Dynamic Frequency Scaling (DFS) which constantly change the cpu freq and it seems to create some instability.

I recommended 1.2 GHz just to insure the system run cool therefore minimizing fan noise.

[dieKatze88 5]

It didn't stay as stable as we thought. Unfortunately the serial console failed at some point. I'll reconnect with it and try to keep it up again to see if I can catch it crashing again. At least it lasted about 30 hours this time.

[clostro 9]

May I suggest outputting dmesg live to a network location?

I'm not sure if the serial console output is the same as 'dmesg' but if it is, you can live 'nohup &' it to any file. That way you wouldn't have to keep connected to console or ssh all the time. Just don't output it to any local file system as writing to a local file system at a crash might corrupt it and cause more problems.

 

nohup dmesg --follow > /network/location/folder/helios64-log.txt & 2>&1

exit

 

needed to have single >, and exit the session with 'exit' apparently..

I did manage to catch the output for the 3rd crash yesterday.
