This workstation - an HP dc5750 panics if you try and boot with ACPI
enabled. I realise that there is another problem with these machines
relating to the SMAP as reported in 111952, but this appears to
be different. I see the SMAP probelem if I boot in amd64 (with or
without ACPI enabled) but under i386 it simply panics before even
getting to that stage.
I am using the latest BIOS from HP, and a version of -STABLE
from two days ago (November 6th).
Attempt to boot a 6.3 kernel on one of these machines with ACPI
Disabling ACPI enables the machine to boot - but it then requires
the amount of physical memory to be set by hand in loader.conf
and cannot see the 2nd processor.
