So here's my problem:
Performance, especially when switching/launching/killing apps is awful,
and dmesg spits out:

Badness in try_to_wake_up at kernel/sched.c:722

C'mon people, this has been reported at least four times ;-)
I'm sure Andrew is looking into it right now.

I get the same message myself when using xmms.

AFAICS this is not much to worry about. It is only a new debug message which did not exist in 2.6.2-rc2 or earlier.
