nouveau_dmesg_before_xorg

I'm trying to use nouveau on integrated 6150SE [1].
Gentoo distro.
linux: today's(2009-07-21) merged linus/master + nouveau/master

When I modprobe module - I get black screen. Starting Xorg does not help (according to logs all OK). UMS mode worked mostly fine for me some weeks ago. Then it become quite unstable (xorg crashes in pixman), I temporarily switched to vesa and didn't try it since.

Attaching:
* dmesg before Xorg start
* Xorg.o.log
* dmesg after Xorg shutdown

Do you have a backtrace of the crashes in pixman?

Thanks.

Nope. I think it's a nouveau's problem at that time. Those segfaults were quite rare (~30 minutes after X start) and didn't appear in vesa. I switched to UMS+nouveau again to catch them again. Will report if any occur.

Xorg survived typical day workload, so I'm taking back my whine about pixman crash.
