dump in /sys/class/drm/card0/error
System: Debian Jessie (testing) 64bit
kernel: Debian 3.13.7-1 x86_64 GNU/Linux
DE: KDE 4.11.3
CPU: Intel i5-4440
mainboard: Asus Z87-plus
monitor: 1980*1200@60Hz via DVI + CRT1024*768@85Hz via VGA/DSUB
no graphical card added
Yesterday I turned on the standard graphical effects on KDE for simple testing
and I halted the system.
Today, after some hours of job, I opened Iceweasel, Icedove, Virtualbox & one
VM and I entered on a Google's hangout to have a videochat.
During videochat,
1) I pressed ALT+TAB to switch to another window
2) I saw the graphical effect "Scambiatore circolare" (this is the italian
translation: I'm sorry, but I don't find the exact english name of this
effect!)
3) I didn't see all windows of programs opened
4) the system freezed some moments (more or less one second).
This is the first time I see this, whit DVI monitor.
Before today no problem whit a 19" TFT monitor plus CRT.
This is on my dmesg:
[20044.219079] [drm] stuck on render ring
[20044.219082] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[20044.219083] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[20044.219084] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[20044.219085] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[20044.219085] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[20044.221558] [drm:i915_set_reset_status] *ERROR* render ring hung inside bo
(0xad9e000 ctx 1) at 0xad9e004
Attached /sys/class/drm/card0/error dump file (compressed).
