After latest update to kernel 5.17.2-1 today, boot shows ACPI BIOS Errors:

Previous 5.17.1-1-default did not show these. I added "acpidump > acpidump.raw"
to this error report.

uname -a shows:
Linux quippy 5.17.2-1-default #1 SMP PREEMPT Sat Apr 9 06:30:15 UTC 2022

Does not seem to be a show stopper, but something changed and could be wrong
now so someone might want to look into this.
