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:

Jan  2 03:35:34 localhost kernel: [ 1164.433117] radeon 0000:01:05.0: 
GPU lockup CP stall for more than 10000msec
Jan  2 03:35:34 localhost kernel: [ 1164.433121] radeon 0000:01:05.0: 
GPU lockup (waiting for 0x0000000000000003 last fence id 0x0000000000000002)

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

regards
Antti
