compressed version of [drm] GPU crash dump saved to /sys/class/drm/card0/error
Several actions like playing steam games in a window for a while or performing
any number of actions in a Chromium window can result in this. It happens
often, up to several times a day. There used to be a kernel panic error on my
system which I am pretty sure has been "replaced" by this error now in which
the system will only freeze for a short time. It seems as if the freezing is
interrupted by ALT+TAB. Then a KWin Window Manager notification will appear
telling me "Desktop effects were restarted due to a graphics reset", inspecting
that notification for further detail states: "Compositing has been suspended |
Another application has requested to suspend compositing" and "Graphics resect
| A graphics reset event has occured".
The application themselves usually do not crash. Sometimes the system is able
to continue performing, other times windows cannot be brought back to front or
into background or minimized, effectively freezing any further user interaction
other than rebooting.
I know of no easy way to replicate the problem. dmesg told me "[ 137.796122]
[drm] GPU crash dump saved to /sys/class/drm/card0/error" and so I am attaching
that file.
My architecture is x86_64. My kernel is 4.2.0-27-generic. My Linux distribution
is Kubuntu. My motherboard is an ASRock Z77 Pro3. Display connector is HDMI2
connected primary 1920x1200+0+0 (normal left inverted right x axis y axis)
160mm x 90mm.
Please note that I tried to get a lot of other information according to
<a href="https://01.org/linuxgraphics/documentation/how-report-bugs">https://01.org/linuxgraphics/documentation/how-report-bugs</a> but the only other I
am able to provide is output from xrandr --verbose. Trying to get Intel
Register Dump, dump VBIOS, or GPU error state have resulted in "Permission
denied" messages. I am not comfortable with editing the kernel command line
myself yet.</pre>
