Dagnabbit.. it's done it again.. went from 100-200 wakeups/sec

Somethings broken in there, but I don't know what.
Or how to make it happen on demand.. it's fine after rebooting again.

At least now I know to look when I hear the fan turning on

2.6.23 did not have this problem.
actually we have reports of 2.6.23 having the exact same problem.
The thing is, "something" is causing the system to go into a state
where the cpu throws us right out of the C-state the kernel asks for.

Ahh. Okay, this machine here did not have the problem on 2.6.23.
Some people have seen that not loading yenta at all will just make this
not happen at all...

No yenta/cardbus here -- it's all PCIe.
If you have any debug patches that could detect or help next time I see it,
then feel free to toss them this way.
Cheers!
