kern.log

When I load the nouveau drm module with modeset=1 on my G86 [GeForce 8400M GS],
the kernel crashes. Backtrace attached.

Workarounds:

1. With modeset=0, nouveau works
2. If I start Xorg with the nv driver, stop it, and then load nouveau with
modeset=1, KMS works without problems. I can start Xorg with the nouveau driver
after that.

Looks like it could be a duplicate of 23712, which has just been fixed. Could
you try again with git kernel?
