Description Antonin Roussel 2020-01-29 21:18:10 CET 
Description of problem:
My display got frozen, impossible to jump to a tty until pressing Alt+SysRq, Alt+R, Alt+E, Alt+I.

How reproducible:
I would say : every time I use too much swap (firefox + vbox + graphic softwares gimp hugin ...)

Steps to Reproduce:
1. let the swap swell
2. graphical crash
Comment 1 Antonin Roussel 2020-01-29 21:20:27 CET 
Maybe some useful information picked from systemctl. But right now /sys/class/drm/card0/error is empty.

# journalctl --system -U "2020-01-29 20:40" -S "2020-01-29 20:26"

kernel: i915 0000:00:02.0: GPU HANG: ecode 9:1:0x00000000, hang on rcs0
kernel: GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
kernel: Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
kernel: drm/i915 developers can then reassign to the right component if it's not a kernel issue.
kernel: The GPU crash dump is required to analyze GPU hangs, so please always attach it.
kernel: GPU crash dump saved to /sys/class/drm/card0/error
