Reaching the desktop in v2.6.38-rc5 I only see the background.
No Icon,widgets,windows etc. I am under the impression
that everything is there - but invisible.
HW is Thinkpad T43 with Mobility Radeon X300 graphic.
Switching to the command line I see drm:radeon
displaying permanently :
drm:radeon_cs_ioctl error invalid command stream
drm:r100_cd_track_check no buffer for AA resolve buffer
I bisected the problem to:
fff1ce4dc6113b6fdc4e3a815ca5fd229408f8ef is the first bad commit

drm/radeon/kms: check AA resolve registers on r300
This is an important security fix because we allowed arbitrary values
to be passed to AARESOLVE_OFFSET. This also puts the right buffer address
in the register.
