As of Linux 6.7 I’m getting hard freezes that require a power cut to reset (sysrq doesn’t work.) Happens at both idle and load anywhere from 5 minutes in to an hour. Running journalctl --follow and dmesg -w (both as root) reveal nothing at the time of the crash. Kernel version 6.6 continues to be 100% stable.
System:
- Distro/Kernel: Arch Linux 6.7.arch3-1
- CPU: AMD Ryzen 5 2600X
- GPU: AMD RX580 8GB via AMDGPU
- RAM: Some configuration of 16GB at 2667 MT/s.
- WM: SwayWM
I’m unsure how to go about properly reporting a bug if no errors are being generated.
Any advice?
I’m not alone on this apparently (warning, it’s reddit.)
This is what I’ll try next. I do think memory is the problem now that I’ve had a few more hours of research. Kernel 6.7 has issues with elevated RAM usage, so it’s absolutely doing something funky with memory that might be exposing underlying hardware issues. I also realized my stable kernel was a version or two away from 6.6.13 (6.6.10), so I’m running it now to see if the issue was introduced late in the 6.6 release cycle, which would be easier to bisect than 6.7.
