It appears to be an acpi issue since passing acpi=off has made the problem go away (at least so far). I've also tried passing acpi=noirq , acpi=oldboot , noapic , nolapic , noirq (of course one at a time) - but none of those helped. Turning off the entire acpi stack seems extreme and I'd rather not do it. Besides, turning off acpi causes my touchpad to stop working.
