Bug ID: 106434 Summary: Graphical hangs, no keyboard, rest of system still active Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: koz.ross@retro-freedom.nz
Created attachment 139418 --> https://bugs.freedesktop.org/attachment.cgi?id=139418&action=edit Relevant fragment of dmesg when this occurs
I sometimes (for seemingly no reason at all) have the graphics completely hang on my machine. I lose my keyboard as well, although my machine is still running (I can SSH into it and everything else still works). I can still move the mouse, but nothing visual responds (I can't click on anything, can't change active windows, etc).
Some additional points of interest:
- My DisplayPort monitor blacks out in such a case, while my DVI monitor keeps working (displaying the same still image) - Killing X or my WM has no effect on this once it occurs (only a restart fixes it) - I can't determine if any particular thing triggers it (seems totally arbitrary)
I've attached a dmesg fragment from one such incident, as well as other pertinent information. Its mention of AMDGPU is why I reported this bug here.
