oops in 2.6.11: "XFree86[2780] exited with preempt_count 1"

[Giacomo A. Catenazzi]

An oops in last kernel. I happens on early shutdown.

I had two other oops in last week (with latest bk tree), but
I was hard crash (still in X) and without any logs.
Because of these thee crash (over some more restart), I think
the bug is probably reproducible.

BTW, there is an extra space before "<6>note"
