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).
