Should be fixed with this patch: http://cgit.freedesktop.org/~airlied/linux/commit/?h=drm-fixes&id=12d518...
*** This bug has been marked as a duplicate of bug 40103 ***
No, it doesn't solve the screen corruption at both boot time as well as while starting Xorg.
I installed new kernel from Ubuntu's builds - so now I'm running 3.1.0-2.3 - the current HEAD of http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-precise.git;a=summary
This is rebased to v3.1 from Linus' tree.
The ubuntu-precise tree already has the commit you mentioned: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-precise.git;a=commit;h=12d5180b...
The severity of lockups seems to have reduced - however, I haven't tested it thoroughly yet. It still locked up while starting Xorg/KDM, but I could at least switch to tty1 and stop KDM. I started KDM after a while and it started properly. Also, dmesg didn't show any more "GPU lockup" messages after KDM started properly.
Is it possible to load radeon.ko with some debug setting enabled? so that it can dump more verbose messages - if that helps you. "modinfo radeon" doesn't show any "debug..." parameter that can be used.
Not uploading new screenshots since there are no changes - (b) and (d) from earlier screenshots is what I got when booting into the new kernel.
Attaching the new dmesg after this comment.
