Title:
  creating ext2/3 fs on cryptsetup/luks usb hdd partition hangs system

Status in “cryptsetup” package in Ubuntu:
  Confirmed

Bug description:
  What I did:
  using an external USB HDD 500Gb (Hitachi 3.5")
  created a single linux partition via cfdisk
  formatted disk with mkfs.ext3 for testing -> works

  cryptsetup:
  $ losetup /dev/loop1 /dev/sdb1
  $ cryptsetup luksFormat /dev/loop1
  $ cryptsetup luksOpen /dev/loop1 usb500

  device /dev/mapper/usb500 exists, so this far is fine

  now watch this:
  $ mkfs.ext2 /dev/mapper/usb500

  After writing 600-800 of about 3700 blocks, the system freezes. This
  is repeatable.

  Second time I had gdm running and did this on tty1, so I got some
  system messages that hint at not having enough memory (though I have
  2Gb working) and thus it started killing processes like gnome-panel,
  etc.

  I did repeatedly format external usb disks that were luks encrypted

  System Information:
  IBM Thinkpad T42p @1800Mhz
  2Gb Ram
  Ubuntu 9.04
  cryptsetup 1.0.6
  mkfs (util-linux-ng 2.14.2)
