Hi there

I have installed following software:
- nouveau DDX driver - from git;
- libdrm - from git;
- linux kernel 2.6.38-rc1;
- xorg - 1.9.2 from debian instalation

And with all this stuff X hangs after some time. I can't realise what is the
cause of these hangs but it happened two times after starting KDevelop 4.0.2.
There is nothing special/extraordinary in dmesg. Actually hangs only X and
graphic subsystem. I can reboot the system with SysRq magic button :) (any
other key combinations don't work) and also I can ssh to my box from other one.

You can find stack trace with which X fails in attached Xorg.log
