Comment(by wdc):
We have more insight:
The root cause seems to be a bad interaction with the enablement of
"C States" in the "Performance" BIOS menu. This option is only available
for high end processors, and appears to have gotten turned on for MIT
machines because we wanted the maximum Energy savings.
Clearing this bit is a work-around for the problem.
