Please see the above URL for dump output etc.
Binary package hint: xorg
latest drivers installed by either distro repo or by the installer
with Ubuntu maverick fail often and regularly.
Always reproducable using x264 video and vdpau output via mplayer and
doing resizes ff/rwd of video.
Also occurs doing simple things (open firefox/ view menu of
DPMS "off" makes slightly more stable although still crashes with mplayer test.
Have tested against 2.6.35-17 and 2.6.35-19 maverick amd64 kernels.
Have also tested with xorg-edgers ppa xorg versions but with same results as described here.
System hangs, often still able to get in via network, however doing
intensive things (cat large syslog ) will hang the process.
Xorg and any offending triggering application cannot be killed
manually. gdm restart also does not work.
shutdown now and reboot will not trigger reboot. Power must be cycled.
Attached are various dump I was able to obtain during a freeze.
nvidia-bug report hangs during collection so may be incomplete.
Also the ABI for the 256.44 drivers is out of date and needs updating,
but this is a seperate issue to the general instability.
Have attempted using xorg-edgers ppa with same result. Also attempted
to use the 256.35 drivers but it complains of missing linux-vdso.so.1
library and X does not load.
