Created attachment 112143 [details] 'hardinfo' report Machine hangs for few seconds with following entries in dmesg: [ 1441.820525] [drm] stuck on render ring [ 1441.820532] [drm] GPU crash dump saved to /sys/class/drm/card0/error [ 1441.820533] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [ 1441.820533] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [ 1441.820534] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [ 1441.820534] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. (File '/sys/class/drm/card0/error' is empty)
/sys/class/drm/card0/error is never empty; ls lies. Please try $ sudo cat /sys/class/drm/card0/error | gzip > error.gz and attach error.gz
Created attachment 112182 [details] Missing 'error' file You are right - it wasn't really empty.
It has to be captured after the hang and before the next reboot.
Oops! I'm sorry - I didn't checked it. I will post one as soon as it happens again.
Created attachment 112430 [details] Fresh 'error' file.
