No, it's not impossible, as noted, acpi=off works. What I need to find out is if it's only a portion of the acpi subsystem that is causing it, so we can disable that portion on this type of machine.

If you can reproduce it, please add libata.noacpi=1 to your boot command line and test that for me. Also try acpi=noirq.
