Added this and it made no difference at all.  Locked up completely. 
This is with a latest cvsup:

Then I plug in...

umass0: USB Mass storage, rev 2.00/2.00, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <Memorex USB2 Thumbdrive 2.00> Removable Direct Access SCSI-2
device
da0: 1.000MB/s transfers
da0: 125MB (256000 512 byte sectors: 64H 32S/T 125C)

mount it, write to it, then hard lockup with no debug or anything.  I
just added a firewire card, though.  Could my system now be sending
debug out that way?  I haven't looked into setting up fw debugging yet
but that is why I bought the card.

I have in my kernel config:

options         KDB                     # Enable kernel debugger
support.
options         DDB                     # Support DDB.
options         GDB                     # Support remote GDB.
