I don't think this is the same issue, but in both cases it looks like 
the BIOS AML code is wrong (just judging from the output, haven't looked 
at the dump yet). _WAK is supposed to return a package of 2 DWORD 
values, a bit field of conditions that occurred during sleep, and the 
effective S-state the system actually entered (section 7.3.7 of the ACPI 
3.0 spec). Presumably the BIOS is returning a single integer.
