I wonder if this is similar to something I've seen, which I think was
eventually categorized as an interrupt-sharing problem.  On my systems,
the graphics locked up, along with USB mouse, and on one of them an
internal disk interface also had timeouts during the "freeze".  All
the affected devices were sharing the same IRQ.

You can see what OI thinks your laptop is doing, interrupt-wise, via:
	echo "::interrupts -d" | mdb -k

I'm not sure how one can fix it.  I was able to disable enough USB ports
in the BIOS on one machine to alleviate the IRQ-sharing, and the problem
stopped happening there.  Here's the (closed) bug report:
