/sys/class/drm/card0/error
I don't exactly know what happened but I found this in my logs:
Apr 28 09:29:45 simon-laptop kernel: [140726.749554] [drm] stuck on render ring
Apr 28 09:29:45 simon-laptop kernel: [140726.749859] [drm] GPU HANG: ecode
9:0:0x87d6fffe, in Xorg [25978], reason: Engine(s) hung, action: reset
Apr 28 09:29:45 simon-laptop kernel: [140726.749861] [drm] GPU hangs can
indicate a bug anywhere in the entire gfx stack, including userspace.
Apr 28 09:29:45 simon-laptop kernel: [140726.749862] [drm] Please file a _new_
bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Apr 28 09:29:45 simon-laptop kernel: [140726.749863] [drm] drm/i915 developers
can then reassign to the right component if it's not a kernel issue.
Apr 28 09:29:45 simon-laptop kernel: [140726.749864] [drm] The gpu crash dump
is required to analyze gpu hangs, so please always attach it.
Apr 28 09:29:45 simon-laptop kernel: [140726.749866] [drm] GPU crash dump saved
to /sys/class/drm/card0/error
Apr 28 09:29:45 simon-laptop kernel: [140726.751659] drm/i915: Resetting chip
after gpu hang
Apr 28 09:29:47 simon-laptop kernel: [140728.749834] [drm] RC6 on
I searched my logs for previous GPU hangs and found another case on April 1st
with the same "signature":
Apr 1 21:07:25 simon-laptop kernel: [ 3281.489363] [drm] GPU HANG: ecode
9:0:0x87d6fffe, in Xorg [4906], reason: Engine(s) hung, action: reset
So not a frequent issue but I thought I should still report it.
