Yes, here is the config (currently I'm using FreeBSD 6.0):
http://80.50.250.246/siano/forum/SYS-acpi-as-module.txt
When I compile acpi directly into the kernel, I've got panic with the
same message as above (pmap_mapdev...).
Unfortunately I can't do backtrace, because kernel didn't mount disk
*before* panic, I will try to move function responsible for mounting
root device before pmap_mapdev().
Sorry, if my english is terrible, but I come from Poland.
Regards.
