Gigabyte K8-NF-9: FreeBSD hangs / freezes when I attach a firewire disk

[Torfinn Ingolfsen]

More info about this problem. I didn't get any responses, should I take this problem elsewhere? If so, where?

The machine is now upgraded to -stable:
root at kg-fil# uname -a
FreeBSD kg-fil.kg4.no 6.1-STABLE FreeBSD 6.1-STABLE #8: Sun May  7

This problem is still there, with exactly the same symptoms.

The disk in question is a Maxtor OneTouch II, 300GB, and it has both
firewire and usb interfaces. If I attach the usb interface, I get the
following in /var/log /messages:
May 13 18:17:53 kg-fil kernel: umass0: Maxtor OneTouch II, rev 2.00/2.03, addr 2
May 13 18:17:53 kg-fil kernel: umass0: Get Max Lun not supported (STALLED)
May 13 18:17:53 kg-fil kernel: da0 at umass-sim0 bus 0 target 0 lun 0
May 13 18:17:53 kg-fil kernel: da0: <Maxtor OneTouch II 023g> Fixed Direct Access SCSI-4 device 
May 13 18:17:53 kg-fil kernel: da0: 40.000MB/s transfers
May 13 18:17:53 kg-fil kernel: da0: 286188MB (586114704 512 byte sectors: 255H 63S/T 36483C)

and if I try to mount it, I get:
May 13 18:18:33 kg-fil kernel: mountmsdosfs(): disk too big, sorry

which is expected, as I don't have the
options	MSDOSFS_LARGE
in my kernel config.

The problem is that the machine hangs / locks up when I try to use the firewire interface.  How do I debug this?
I mean, even the local console is frozen / hung.

Any hints / suggestions welcome.
