GPU crash dump saved from /sys/class/drm/card0/error

Screen freezes for about 30 seconds causing my window manager KDE 4.13 to
restart the rendering engine. Happens on a regular basis and it is highly
annoying, but is hard to reproduce. It occurs most often when using the Chrome
web browser (but not only).
