--- Comment #21 from Kunal kunal.gangakhedkar@gmail.com 2012-08-15 15:41:05 UTC --- Unfortunately, this patch on its own doesn't fix the problem for me. :(
I also noticed a new commit with reference to this bug in Linus' tree when I synced my git tree: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=81ee...
So, I cherry-picked this patch on top of commit 0937d042b97a9540b5488ab172aa14b53e80014b of Ubuntu's quantal tree from: git://kernel.ubuntu.com/ubuntu/ubuntu-quantal.git
and built the new kernel from it on 15th Aug., 2012.
And it still doesn't solve the problem for me :( The behaviour remains the same.
Anything more that I can try?
I tried to apply this patch on top of commit 81ee8fb6b52ec69eeed37fe7943446af1dccecc5, but it fails to apply at all.
I'm now starting to wonder if it's really a driver issue or whether I have gotten a bad card. But, the fact that I can switch to tty (after repeatedly hitting ctrl+alt+f1 for about 30-40 times in fast successions) and then restart kdm without any artifacts suggests that the card is fine. Could it be some race condition being triggered?
Attaching the dmesg output.
