Changing to acpi=off did not fix the problem. I'm a little concerned
with whether it's really off though, it seems to turn on local apic

Oct 29 08:56:54 mythtv kernel: Kernel command line: auto

Oct 29 08:56:54 mythtv kernel: bootsplash: silent mode.
Later, it does say:

but it doesn't say anything about local apic again. How can I check
that it's really disabled?
If you have a relatively nice BIOS, it will enable you to disable ACPI,
LAPIC, and possibly APIC. Try that in addition to the kernel params.
