Before and after peek 10a000 on ION2

Here are 3 more peeks, before and after, using a different chipset as you said
that might be interesting to you.

    Kernel driver in use: nouveau


I do see messages in the kernel, but as you mentioned it's a separate bug. They
appear inconsistently during this failure.
[drm] nouveau 0000:01:00.0: PFIFO_DMA_PUSHER - Ch 2
and sometimes also:
[drm] nouveau 0000:01:00.0: PGRAPH_DATA_ERROR - Ch 2/2 Class 0x502d Mthd 0x0240
Data 0x00000000:0x00086184
[drm] nouveau 0000:01:00.0: PGRAPH_DATA_ERROR - INVALID_VALUE


This is on openSUSE Factory, kernel 2.6.36-rc4
xorg-x11-server-7.5_1.9.0.902-69.3.x86_64
xorg-x11-driver-video-nouveau-0.0.16_20101010_8c8f15c-14.1.x86_64
