IMO it's yet another incarnation of

If this is an outright violation of the ACPI spec, let me know (and if
possible, please tell me the spec page). This is the kind of thing I expect
it would be a no-brainer to get Lenovo to fix with a BIOS update.
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.
