Wait a minute, this looks painfull similar to this issue:
> PCI: Using configuration type 1 for base access
> bio: create slab <bio-0> at 0
> ACPI: SCI (IRQ20) allocation failed
> ACPI Exception: AE_NOT_ACQUIRED, Unable to install System Control
> Interrupt handler 20090521 evevent-161
> ACPI: Unable to start the ACPI Interpreter

where a patch from upstream fixed the problem.
