DMESG output showing hardware info and lockup.
Playing back MPEG-2 compressed video causes a GPU lockup and reset. This
happens about 9 times out of 10 upon start of playback - the other time
playback starts fine.
About 4 out of 5 times the reset is successful and playback begins a catchup
phase before continuing normally - otherwise it results in a complete system
freeze.
If playback actually starts it continues fine.
Using VDPAU assisted playback via XBMC. Using software only playback works fine
every time. h264 playback seems unaffected.</pre>
