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
