Bug Description
This is an absolute freeze. Mouse, sound (often repeats a small bit of what was played), keyboard freezes. No other TTY can be started. I can not SSH into the frozen computer.
Starting virtual machines or running heavy makefiles will induce this freeze, though not reliably. It often takes a couple of tries.
When the freeze has happened, if let alone, the laptop will shut itself down because of the heat (reported by kern.log).
It has happened with kernels from pre-proposed kernels (2.3.0-27 to 2.3.0-31). Have now installed the default kernel and freezes persist.

This is what the kern.log looks like before and after a freeze.
I have commented on where the freeze happens.
