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?
