Disabling ACPI and APM in the host OS had the unfortunate result of
causing it to cease to communicate with the SATA chipset.  Therefore,
that solution did not work.

I have, however, found a combination that seems to be stable.  I
disabled Cool & Quiet in BIOS -- evidently setting the CPU frequency
governor to `performance' was not adequate.  Combining this with the
el5vm kernel with "noacpi nosmp noapic nolapic clocksource=pit" in the
guest seems to work.
