Package: linux-image-686
Version: 2.6.32+25
Severity: normal


Code path for r100/r200 is missing GPU cache flush in GPU context
swicth. This causes image corruption and possible GPU hangs.

Fix is included in 2.6.33 since commit:
9e5b2af75abc67c13005c706cf95bbbb78f7fddc drm/r100/kms: Emit cache
flush to the end of command buffer.

It would be good idea to backport it to debian kernels vefore 2.6.33
tht hae kms enabled for radeon (like 2.6.32 in sid)

This is a metapackage and has few bugs of its own.
