The BIOS latency values look sane, I wonder why my patch helps.
Because I am blindfolded..., this is about reducing up_threshold and
it is a a duplicate of bug #17001.
Can you try to lower up_treshold to 53 or below as mentioned there and then use
cat /dev/zero >/dev/null &
multiple times to utilize CPUs.

Looks like something broke somewhen before 2.6.35.7.
Do you know about a kernel version that did not show this?
