I ended up also that same commit after bisecting from current 3.8

01:05.0 VGA compatible controller: ATI Technologies Inc 760G [Radeon

I cannot even boot unless graphical boot is removed from Fedora 17
boot options (rhgb quiet). Random GPU crashes still.

You could try the temporary R600-only fix although I can't see whether
your GPU is also an R600 ASIC or something different by staring at the
model string above:



How do you trigger the issue ? Does it happens right away on boot ?


Sorry for utterly unclear description. I meant it randomly crashes desktop in case I got it booting by removing graphical boot option. In that case Cinnamon desktop "freezes", I was able to move mouse cursor but clicking buttons or moving windows etc. didn't worked at all. Only mouse cursor moves. It was possible to switch to console by ctrl+alt+fN.

When Fedora graphical boot was enabled (options rhgb quiet) and I selected Kernel from the grub, it makes just blank screen and after 10sec or so monitor switches off saying "no signal". Nothing happened after that, boot was forced. I use dm-crypt and normally about the first thing is to show is graphical lock screen asking passphrase.

I did some grepping from the syslog and that same message is seen:

After I reverted bisected patch it has been working just fine. I has been running whole day without problems.
