Sworddragon, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Title:
  Mounting as minix can block a long time

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm using Ubuntu 13.10 dev with mount 2.20.1-5.1ubuntu8. Forcing to
  use minix as filesystem on mounting a device which has another
  filesystem and doing another disk operation on the physical device
  will cause mount to block until the disk operation is finished. Here
  is an example:

  1. As preparation clean the cache with "echo 3 > /proc/sys/vm/drop_caches".
  2. Execute "mount -t minix -v /dev/sda5 /mnt & find / > /dev/null" (dev/sda5 is a swap partition and / is /dev/sda1 (ext4)).

  Because /dev/sda5 is a swap partition theoretically the mount
  operation should fail in a short time. But mount waits until the find
  command has finsihed which can need a long time. After this the
  following error is shown (as expected):

  root@ubuntu:~# mount: wrong fs type, bad option, bad superblock on /dev/sda5,
         missing codepage or helper program, or other error
         In some cases useful info is found in syslog - try
         dmesg | tail  or so

  
  Replacing minix with ext4 on mounting works fine. The mounting operation will fail too but this needs less than a seconds instead of a few minutes. It is even conspicuous that without another disk operation mounting as minix needs a few times longer than other filesystems. I'm assuming there is something broken on the minix module with checking for bad filesystems.
