 The machine currently runs FreeBSD 6.2-stable:
 root at kg-fil# uname -a
 FreeBSD kg-fil.kg4.no 6.2-STABLE FreeBSD 6.2-STABLE #20: Mon Mar 12 23:04:49 CET 2007     root at kg-fil.kg4.no:/usr/obj/usr/src/sys/FIL60  amd64
 
 and the problem still exists there.
 
 However, I did try booting off a FreeBSD 7.1-release / amd64 livefs cd. With 7.1-release, the machine doesn't hang, bot the console fills up with messages:
 fwohci0: phy int
 
 and the disk never attaches. I can detach the disk and attach it without the machine hanging (but lots of "phy int" messages when the disk is attached). I guess that's a bit of progress.
 
 Missing from my first report was the make of firewire controller:
 root at kg-fil# pciconf -lv | grep FireWire -B 4
 fwohci0 at pci1:10:0:	class=0x0c0010 card=0x10001458 chip=0x8025104c rev=0x01 hdr=0x00
     vendor     = 'Texas Instruments (TI)'
     device     = 'TSB82AA2 1394b OHCI-Lynx IEEE 1394 Host Controller'
     class      = serial bus
     subclass   = FireWire
