Yeah, it just crashed on me again. So I was just lucky. I also tried disabling
dynclks and dpm, no effect. What I did differently yesterday is I had very
litte browser (Debian Iceweasel) usage. Today I had some Youtube running when
the crash happened. In fact the crashes happen most time when whatching stuff
on Youtube, i.e. when Iceweasel uses vdpau through gstreamer. I now removed
mesa vdpau drivers. I will report back if this changes anything.
