git bisect log

Hi,
mesa crash as soon as I start xorg with 'startx' from tty1.

I can see the mouse coursor in the middle of a black screen.
After a few seconds the tty1 appears back, the message tells me that my GPU
hangs for XXXX seconds.

I tried to bisect this and you can see the result attached.
I've also attached my mesa build script.

My GPU is a R7-265 pitcairn, running Debian sid, with mesa/xorg/drm/kernel from
git.
LLVM 3.8 is at revision: 257294.
I'm usign LXqt+openbox from debian sid.</pre>
