System crash - nothing in journalctl

I am getting random crashes of my system which I am struggling to debug. I am beginning to think it may be a hardware issue. The system will randomly hang: any music playing will just start looping a small segment; the mouse and keyboard become unresponsive;

most importantly: SysRq + REISUB doesn't work. The appropriate values are set (kernel.sysrq=1).

I have to do a hard restart, with all the ensuing orphaned inode messages.

Subsequently checking journalctl for the previous boot shows absolutely nothing within minutes of the crash to help me identify the problem.

I am at a loss.

Kernel: Linux 6.10.10-arch1-1
WM: Sway (Wayland)
AMD Ryzen 9 7900
Mobo: ASUSTeK model: PRIME X670-P WIFI

Any guidance much appreciated.

thank you

Re: System crash - nothing in journalctl

Since anything is better than nothing, can you post the journal from such a crash? But if REISUB doesn't work then something very low level will have died. I'd suggest to maybe try linux 6.11 from testing seeing as the HW is quite new.

Do the keyboard LEDs flash?

Re: System crash - nothing in journalctl

I struggle with ryzen 5 5950x glitches, reboots and halts at random load. The first thing make sure running the latest mobo AGESA, it makes a huge difference between each version, try different kernel, scheduler, governor etc. Personally managed to get a relative desktop stability after turned off ASPM completely with pcie_aspm=off kernel parameter. You can also try to play with curve optimiser by setting it to positive values, but these are increasing idle temp much in my case. Ultimately it's a CPU culprit which most likely have too low power during frequency peak.
