Today I got this while starting a video in SMplayer (MPlayer) with 2.6.38-rc6-00113-g4662db4:

Screen was almost freezed, cursor was stuck but the machine was alive and I was able to use SysRq to kill X and try to restart it (but that didn't help).
I don't remember anything similar in recent kernels (<= 2.6.37) and got this only once with 2.6.38-rcX.
Environment at the time of the GPU crash: KDE4 (without "Desktop Effects") Chromium Claws Mail Dolphin ccached make -j3 on a just pulled linux-tree (so I/O bound) SMPlayer/Mplayer (just launched)
Assorted logs attached.
