Yeah!  I've got FreeBSD 8 running for the first time with ACPI enabled
on that machine now.

So the question is why acpi_thermal hangs...  I might also try
swapping the ahc0 controller back now.  Do you have any idea why this
one gets a correct resource allocation with debug.acpi.disabled=sysres
but not otherwise?  Is that rather a bug in the ACPI BIOS or in
FreeBSD?

I could probably live with enabling both debugging options for that
machine, but I'd also like to help avoiding in particular the hard
hang in acpi_thermal since it might perhaps also affect other users.

Thanks a lot for all your help so far, John, it's really appreciated!

Never trust an operating system you don't have sources for. ;-)
