X log of gdm session

modesetting on NV86: text mode goes blank, machine freeze on gdm stop

using branches nouveau/master, mesa/drm/modestting-101 and
nouveau/mesa/gallium-0.1.

I reboot in single user mode, modprobe "drm debug=1" and "nouveau modeset=1".

At this moment, the screen turns blacks but the machine does not freeze. From a
SSH, I can start gdm and it seems to work, though the screen is still black.

When trying to stop gdm, the machine is freezing.

After X start I had many of these lines:

Jul 21 15:48:36 xiong kernel: [  605.062180] [drm] PGRAPH_ERROR - nSource:
PROTECTION_ERROR, nStatus:
Jul 21 15:48:36 xiong kernel: [  605.062APH_ERROR - Ch 2/0 Class 0x502d Mthd
0x08dc APH_ERROR - Ch 2/0 Class 0x502d Mthd 0x08dc Data 0x00000000:0x00000000

(Yeah, I was told not to use the debug option, I typed too fast.)

Adding logs as usual.
