Besides the new messages, I didn’t notice any regressions due to this yet.
Could this be related to commit 57707a9a77 (ACPICA: Resources: Not a valid
resource if buffer length too long) [1]?
I would welcome a hint to the user, what to do, though. Like “This is most
likely a firmware issue. Contact the vendor.” or something similar.
