    Hi with the vfs locking patch removed it works.

    oscar# mount /fuji
    usb-uhci.c: interrupt, status 3, frame# 1622
    SCSI device sda: 131072 512-byte hdwr sectors (67 MB)
    sda: Write Protect is on
    sda: sda1
    oscar# ls /fuji
    dcim
    oscar# umount /fuji
    oscar# umount /fuji
    umount: /fuji: not mounted
    oscar# mount /fuji
    usb-uhci.c: interrupt, status 2, frame# 1448
    I/O error: dev 08:01, sector 0
    FAT: unable to read boot sector
    mount: wrong fs type, bad option, bad superblock on /dev/sda1,
    or too many mounted file systems

    Chris, what I suspect is happening is that the mount with the error leaves
    the sem locked. After this any mount commant hangs - not just ones for the
    USB card read (ie. loop mount to build an initrd fails too..)
