For a N=2, we're having the same issue with a set of OTC machines.

Fallback to the UEFI eventlog is what we did for a short term fix too. Will try to contact the vendor for a fixed ACPI table long term.
Morten: Did you get in contact with the vendor about this? Looks like a class error across different devices.
Cheers,
Erkki
