I would like to confirm that the issue for me is solved by the switch to the last kernel build.
35 days without any issues:
~ $ uptime
13:50:11 up 35 days, 19:27, 1 user, load average: 0.07, 0.18, 0.20
Thanks again to @Igor!
Actually I'm using Armbian running on Rock64 board. Today I successfully did the kernel upgrade and I hope this will resolve the problem.
@Igor, thank you for the info and the detailed instructions how to upgrade the Armbian kernel!
In my case, the problem occurs after prolonged periods of time - about 20-30days uptime. However, it's still annoying to reboot a Linux-based system like a Windows server.
Has anyone else tried the proposed solution with 'zram-config' ?
@kevkkvek, could you please share how is your device running after that change?
