[drm] GPU crash dump saved to /sys/class/drm/card0/error
On my new Zotac ID92 i experience frequent freezes of the graphic output which
last for a few seconds, usually when the GPU is under a bit of load, like
playing a movie, using Chrome (Particulary when using the integrated
flashplayer) or playing a game.
The problem is reproducable and i can provide additional crash dumps if
necessary.
Intel Haswell with HD Graphics 4600
