X.org crashes on current branches

[Tobias Hain]

Hello,

chipset: GM965
kernel: (vanilla) 2.6.28-rc8, (drm-intel-next) of Eric's 2.6.28-rc8
xserver: server-1.6-branch
libdrm: master
mesa: master and intel-2008-q4
xf86-video-intel: xf86-video-intel-2.6-branch

I'm facing X.org crashes when launching X with all of the above:

Fatal server error:
Caught signal 11.  Server aborting

It's always the same crash and related to 3D compositing manager loading I
guess. I tried some permutations of the above branches, but none worked.
Always the same crash that I didn't have before updating the branches. I've
been tracking intel driver development for a while, but not on a regular
basis. I think I updated branches one month old and before that everything
worked fine. xorg.conf doesn't contain anything special.

It's KDE 4.1 compositing manager. Haven't tried anything else yet. Hope it
sounds familiar to some.
