Just upgraded kernel to version 3.8 on my system and several GPU lockups
uccured when I opened pastebin link in Opera browser. (Here is expample link:
http://paste.ubuntu.com/5568971/ or http://paste.ubuntu.com/5568954/). Several
times I opened such several links in Opera and one time it caused GPU lockup
and other times it even freezes. After turning off Opera Hardware Acceleration
there was no lokups. And the thing is that with kernel 3.5 no lockups occured
even with hardware acceleration turned on.

KDE 4.10, desktop effects enabled.
