The log at http://lkml.org/lkml/2008/6/6/317 shows two pauses. One in
the middle of USB related messages with no FireWire stuff around
(17:25:19 to 17:25:44). The other with parport, ieee1394, USB messages
around it (17:25:44 to 17:26:31).

From there, the last 17:25:44 message is strange: The device
00110666000013cc which is the controller is reported as being removed.
Chris, did you do something at this point?

Also, in http://lkml.org/lkml/2008/6/1/2 you reported a patch which
changes the SCSI core's interaction with the driver core as first bad
commit. Did you check that going before this commit removes _all_ the
pauses, even those around USB or FireWire messages? Or did you only
check whether disk drives appear quickly?
