It is January 2023 now, and this bug is still active in kernel 5.15.86.
:(
I am running KDE Neon with self compiled kernel 5.15.x (because it is
marked as "longterm") on a Fujitsu mainboard, equipped with an Intel
Core i5. (See below.)
I wouldn't mind having these messages in the systemlog, as they are
harmless and the system runs without any quirk. But but they appear on
the console as well, even interrupting the splash screen! (Which is a
bit of a humiliation, if there's a Windows user looking over your
shoulder while your machine is booting...)
I know that this is a pure cosmetic complain, but it has been happening
for more than a year now, and I really would like to get rid of this
annoyance. I tried the usual grub command line options like
"loglevel=3"
"acpi_osi=! \"acpi_osi=Windows 2015\""
but neither did suppress these console messages.

Searching the internet shows that many people with different computers
are affected by that.
Probably it's a regression in the Linux kernel as described at:
