Okay I tried out your recent changes this morning.
First I did a svn update to r190540 to bring my sources up to date and
then I built a new 7-Stable world and kernel and installed them. Sadly,
I still got the video mode corruption on exiting X or switching from X
to a VT. I then merged all the changes from head/sys/dev/drm to
stable/7/sys/dev/drm and tried again. Unfortunately, I got the same
results. (Xorg.log and dmesg.boot available if required.) The changes
I merged were: 190020, 190021, 190022, 190023, 190123, 190124, 190125,
190163, 190164, 190166, 190170, 190282, 190399, 190400, 19401 and
190433. Some of these were probably not relevant, but I did everything
to make it easier for me. (I am very much still testing the water with
svn and this was the first time I tried doing a merge!)
Any ideas where to go from here?
Cheers,
Nick.
