I redid this today when I relised that somehow CONFIG_CC_STACKPROTECT (or what
the config option for gcc flag -fstack-protector is called) probably was
enabled last time and I wanted to see if disabling made things work.

The nouveau linux-2.6 kernel freshly pulled (commit
2e68b1d4775b7b773334a4a9c6ef2358bfa85d42).
libdrm (commit a107e5b12960f64722bff424502a4fc0ad33dc8f) and xf86-video-nouveau
(commit 9cbc139176ae991150bd9ddf66b61db471b391f2) freshly pulled from git,
rebuild and installed.
with xorg-server-1.6 it works, with xorg-server-1.7.0{,.901} it fails

X dies with Assert (ret==0) error message.

This time I did it like this.

I have a file in /etc/modprobe.d that blacklists nouveau so I can control when
it will be loaded, adds modeset=1 to it, and adds debug=1 to the drm module.
I also did an [MARK] in the kernl log every time I did something.

I ssh into the machine.
modprobe nouveau
X &
(waited for the machine to settle) gdb --pid=`pidof X`

from another ssh:
DISPLAY=":0" gnome-session


and then I waited for X to crash.
It seems like every gtk+ app has problem displaying stuff. If I start xterm
instead of gnome-session xterm works as it should. No gtk+ apps show stuff it
should. And something gnom-session loads crashes nouveau.

kern.log, Xorg.log and gbd.txt will be find at this address since they are too
big for bugzilla.
