This is the same on FreeBSD - acpi_res_set_iorange() is the function
printing this message. It's been implemented as that way for years.

There's several places in ACPI-CA code where it can display this message,
so I'd look at a verbose dmesg output with the following variables set
at boot prompt(don't try to post it to the mailing list) to find which
function in ACPI-CA code is showing the message:

They're probably as harmless as they are on FreeBSD.
Quickest workaround I can think of is to set
in /boot/loader.conf, but I'm not sure if it has any side effect.
If you're not seeing any problem other than the annoying warning
messages and the LPT port, you can ignore them.
