ACPI Error: Could not disable RealTimeClock events

One of my computers has got a defective quality BIOS, and an upgrade is not going to happen.
On boot I get annoying messages, 'ACPI Error: Could not disable RealTimeClock events ...'
In a console, I do, tail -f /var/log/syslog
In another console I change the clocksource,
echo hpet|acpi_pm > /sys/devices/system/clocksource/clocksource0/current_clocksource
When I change from tsc to hpet to acpi_pm I still get the same Error message in syslog, when I hwclock --systohc.
I think this is a newer kernel bug feature.
I am not going to worry about it.

Re: ACPI Error: Could not disable RealTimeClock events

netinstall 5.0.1 is linux-image-6.1.0-10
since then Devuan has provided 6.1.0-11|12|15|18
the bug feature has arrived with 18
I have determined this by having installed 10|11|12|15|18
I have ran through them all with shutdown -h now and unpugging the power for more than 5 seconds.
I tried kexec-tools which is wicked, but the Error remained up & down the versions?! shady
This bug feature is currently officially reported by others.
It does not bother me but may bother others running ntpsec and many other programs.
It only manifests on certain pieces of crap BIOS & hardware.
