with kernel 2.6.35-rc5 I'm seeing a problem which happens every few
hibernate/resume cycles.
When I resume my computer, X is black (only the mouse cursor is
visible) and the X server outputs a stack trace to the VT. Changing to
the VT and back restores xorg correctly. dmesg says:

This would not happen with 2.6.34. My hardware is a GM45.

any idea what this might be?
