Can you press Ctrl-Alt-F1 to get to a text terminal, maybe kick off
something like a compile (to get the heavy load), and see if it freezes?
You're more likely to get debugging information on a text terminal than
in graphics mode. Press Alt-F7 to get back to graphics mode.

It's worth entering this into bugzilla.redhat.com, too: this means that
the Red Hat kernel developers (hi Dave!) will at least have a record
that there is a problem.

You might also want to play with some of the ACPI options mentioned in
http://www.ibiblio.org/peanut/Kernel-2.6.10/kernel-parameters.txt .

Hope this helps,

James.
