Xorg log

Hello,

I'm in a multimonitor setup. One with 22' and another with 15'
rotated. I used
to setup my screens with xrandr only. However, after updating drm and nouveau
from git and build, It crashes on rotation. I run xinit and run: 

xrandr --output DVI-I-0 --rotate left

And X server crashes with:

Backtrace:

If I use:

 xrandr --output DVI-I-1 --rotate left

It simply freeze. I'll attach the logs for the first case.

Today's build news:

Today I got the same behavior "rotating to left" both screens: crash
and stack
dump. The kernel freezing happens randomly and specially when I try to
VT-switch after a crash.

I also reproduced this on single screen setup. This is not multihead setup
problem. This is "--rotate any but normal" and "--reflect
any" problem.
