On my brand new system and I am experiencing seemingly random system crashes. Out of the blue, the mousepointer will begin stuttering and become very sluggish for about 10 seconds, then the machine just reboots.
At first I ran Gnome, where it happened more or less daily. Then I reinstalled XFCE edition, and now it happens about once a week. That is, I have found a way to reproduce it: If I have Deluge running with a bunch of active torrents, and play a video in VLC at the same time it will happen within 10-15 minutes. When running Deluge only it will crash within a couple of hours.
I also ran Deluge and VLC simultaneously on Windows for 2-3 hours without any symptoms, so I doubt this is a hardware issue.
The log from journalctl does not yield anything interesting as far as I can tell, but really my knowledge of these things is limited. I notice that there is nothing at the exact times when the crashes occur.
In one case while I was running Gnome, I came back from a walk and all the icons on the Gnome desktop had been replaced with dummy icons. When I rebooted the machine GRUB was gone and it booted straight into Windows. The data on the Manjaro-partition was all good, though. Don’t know if these issues are related.
What I have tried:
Disable global c-states in BIOS
This did not help. Also I doubt that this is the problem, since grep . /sys/devices/system/cpu/cpu0/cpuidle/state*/name outputs (without disabled c-states in BIOS):
/sys/devices/system/cpu/cpu0/cpuidle/state0/name:POLL
/sys/devices/system/cpu/cpu0/cpuidle/state1/name:C1
/sys/devices/system/cpu/cpu0/cpuidle/state2/name:C2
/sys/devices/system/cpu/cpu0/cpuidle/state3/name:C3
This means that the max c-state is 3, right? On some systems c-state 6 can cause problems, but that does not seem to be in play here.
Disable NVMe power states
Did this by adding nvme_core.default_ps_max_latency_us=0 to GRUB. Did not help. I assume it is switched off since nvme get-feature /dev/nvme0n1 -f 0x0c -H outputs Autonomous Power State Transition Enable (APSTE): Disabled
Lowering speed of RAM
Tried lowering speed of RAM from 3200MHz (advertised speed) to 2400. Had no effect.
Kernels 5.10.x and 5.11.x
Both of these has the same issue.
CPU stress tests
Running s-tui and Prime95 on Windows for at least 45 minutes made the fan speed up like I have never witnessed before, but did not trigger the issue.
Windows memory check (mdsched.exe)
Reports no errors.
Using another wall socket
The extension cord I was using was one of those with an on/off switch. The switch has seemed to be unstable, so I switched to another wall socket. Unfortunately it did not help.
