When trying to mount a zip disk, the mount process gets stuck:

[root@viper root]# mount -t ext2 /dev/sda1 /mnt/zip
SCSI device sda: 196608 512-byte hdwr sectors (101 MB)
sda: Write Protect is off
sda: cache data unavailable
sda: assuming drive cache: write through
SCSI device sda: 196608 512-byte hdwr sectors (101 MB)
sda: Write Protect is off
sda: cache data unavailable
sda: assuming drive cache: write through

At this point the mount process is unkillable.
Also strange is that the messages are printed twice.
