I've seen several people report ACPI eats disks. ACPI is incredibly complex
badly designed crud. My advice is never use ACPI. This incidentally appears
to be the advice Microsoft give people too - they tell people to disable
ACPI as one of the first steps to diagnosing strange crashes in machines

ACPI is over complex, new technology. The BIOS stuff is new (and frequently
wrong), the kernel stuff is new (and has plenty of known bugs) and the
combination is a recipe for disaster.

I've been discussing with a few folk about doing an alternative mini acpi
subset so that Linux can be booted on most 'ACPI only' hardware without
using all the ACPI junk
