dmesg | grep drm

I am using gentoo with the nouveau-kernel, libdrm from git, xf86-video-nouveau
from git all updated today.
If I use org-server-1.6 it seems to work as it should but because of the
slowness with gnome-terminal I wanted to take a look at xorg-server-1.7.

The problem:
I upgraded to xorg-server-1.7, and have also (for other reasons) rebuilt
everything in my system, so every X-component are rebuilt with the latest
versions installed, including all the drivers.
If I tri to startx, then everything start to loads, except that things does not
look like they should. There are no characters what so ever. Windows borders
are drawn, the background are drawn. The nouspointer are drawn. Some content
fof the windows are particially drawn. Then lockup. No response from keyboard,
no response from mouse.

The system responds to ssh, and with NoAccel everything works as is should,
just a bit more slow.

Attaching Xorg.log and "dmesg | grep drm".
Will see if I can get out a backtrace also if that would be helpful.

Ok, this starts to get more fun.... When I startx it it runs for nearly a
minute, but then (more comment in the bottom).

waiting for X server to shut down 


After this I did gdb X and it was stable.
I started xterm on this display, and it showed up and worked like it should.
I started gnome-session in this xterm.
The xterm-window stayed working, and gnome started to show up. Same problems as
before for the gnome apps. gnome-panel shows patilly some white rectangles,
with black dots in, same with the windows, the borders are all fine, but of the
rest there is not much drawn.

And then it crashes. I will attach a backtrace.

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.

I tried getting vanilla kernel sources, and applying
http://cvs.fedoraproject.org/viewvc/rpms/kernel/F-12/drm-nouveau.patch?revision=1.64
and
http://cvs.fedoraproject.org/viewvc/rpms/kernel/F-12/drm-next-d4ac6a05.patch?revision=1.2
to get the former to compile.

Then I applied 
http://cvs.fedoraproject.org/viewvc/rpms/xorg-x11-drv-nouveau/F-12/nouveau-tile7000.patch?revision=1.7
to my xf86-video-nouveau.

And after this gtk+ applications were working like they should in
xorg-server-1.7.

By disabling the semi-transparent background on gnome-panels also the Assert
(ret==0) crash went away.
