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

Hi,

my linux crashes (complete freeze, recovery only possible with reset button) regularly when watching a movie. It was difficult to reproduce since it doesn't crash consistently at the same time/movie/codec... But I'm able to reproduce a crash now with an open-arena benchmark/test from the phoronix test suite. This time it hasn't been a complete freeze so I was able to gather the GPU crash dump.

here an extinct of /var/log/syslog
