System: NetBSD snoopy.here 2.0_BETA NetBSD 2.0_BETA (GENERIC) #0: Sat Jul 24 01:18:41 UTC 2004 autobuild@tgm.netbsd.org:/autobuild/netbsd-2-0/i386/OBJ/autobuild/netbsd-2-0/src/sys/arch/i386/compile/GENERIC i386
Architecture: i386
Machine: i386
>Description:
	Trying to access an USB memory stick by `mount' takes 7'25".

	Plugging the memory stick yields:

umass0 at uhub0 port 1 configuration 1 interface 0
umass0: USB Solid state disk, rev 1.10/1.00, addr 2
umass0: using SCSI over Bulk-Only
scsibus0 at umass0: 2 targets, 1 lun per target
sd0 at scsibus0 target 0 lun 0: <USB, Flash Drive, 1.11> disk removable

	If the stick is already plugged in during boot the system hangs 
	after the latest message line above.

	After starting `mount /stick' it takes some 3 minutes
	until these lines show up:

sd0: fabricating a geometry
sd0: 64512 KB, 63 cyl, 64 head, 32 sec, 512 bytes/sect x 129024 sectors

	After 7'25" `mount' completes. Another line shows up:
sd0: fabricating a geometry

	Then the filesystem can be accessd.
	
	On the same machine under FreeBSD 4.9 the mount completes quickly.
	Also on a different machine under NetBSD 2Beta the same memory
	stick mounts quickly.

	Dmesg:
