Decided to build my first kernel with preempt since the early 2.5 days. I'm
seeing the same warnings in 2.6.2-rc2-mm1.

gkrellm 0 waking gkrellm: 897 1485
Badness in try_to_wake_up at kernel/sched.c:722

Every five seconds. This is when it reads the sensor information from /sys, I
think. And during boot, similar messages to those already reported (from
kern.log this time).
