Kernel panic with ACPI enabled

[Przemysław Celej]

Hi,

Since I'm using FreeBSD 5.X and 6.X I've got seriously problem with 
ACPI. When I setup ACPI as module, I've got panic soon after kernel 
recognize processor:
pmap_mapdev: Couldn't alloc kernel virtual memory

*but* on GENERIC kernel ACPI works without any problems. I'm convinced 
that, this problem is depending on hardware (actually only on motherboard).

Please help me, I need ACPI enabled.

Environment:
System version: FreeBSD-6.0 (but this problem steps out on FreeBSD 5.X also)
Motherboard: Abit NF7-S (on nforce2 chipset)
Memory: 512MB DDR (333Mhz)
Hard drive: Seagate V 60GB/ATA100
Processor: AMD Athlon2500+/333Mhz
