[Solved] Random system hard locks

Hardware:
CPU: AMD Ryzen™ 7 4800H with Radeon™ Graphics × 16
GPU: NVIDIA GeForce GTX 1650 Ti

dmesg:
https://0x0.st/HFfr.txt

I have tried disabling Zswap, but the issue persists.

Check your RAM health with memtest: https://wiki.archlinux.org/title/Stress … MemTest86+

I ran Memtest86+ overnight for approximately 7 hours, and it successfully passed all tests.

The Magic SysRq key does not respond when the issue occurs. The console repeatedly displays the message 'watchdog detected hard lockup on cpuXX'.

Re: [Solved] Random system hard locks

I have tried disabling Zswap

Tried or succeeded?
The dmesg errors show issues to load pages from zswap and ultimately another page fault.
You also have zram enabled what will cause a collision (and the dual-use is pointless to begin with, see the wiki)

Otoh there seems no genuine swap device, add a swapfile to make sure you're not just OOM.

Finally there're reported issues w/ nvidia 550xx, but the stacktraces look vastly different, https://bbs.archlinux.org/viewtopic.php?id=293768

Re: [Solved] Random system hard locks

I discovered that the issue was indeed related to the Nvidia driver. After disabling zram and zswap, the stack traces look similar to the reported issues. Thanks!
