Title:
  LUKS partition corrupted

Status in “cryptsetup” package in Ubuntu:
  Expired

Bug description:
  Ubuntu 9.10 (karmic) x64

  After installing a recent set of updates (including any from
  -proposed), among others a kernel update (i don't recall the other
  ones), my main LUKS partition (containing /) has been corrupted. After
  rebooting, I am no longer able to boot the system because of
  cryptsetup idling with "Waiting for encrypted source device..."
  forever.

  Trying to "cryptsetup luksOpen" from a live-CD fails as well:

  > ~ $ sudo cryptsetup luksOpen /dev/sda7 crypto
  > Enter LUKS passphrase: 
  > Command failed: /dev/sda7 is not a LUKS partition

  Unless this is the unlikely event of some kind of hard drive failure
  at the exact same moment (seems unlikely as I can boot into other OSes
  from the same HDD just fine), this seems to be quite a serious bug.

  I'm attaching the output of "hexdump -C -n 1024 /dev/sda7" which still
  seems to contain something that looks like a LUKS header. I've no idea
  where the grub stuff comes from and if it's supposed to be there or
  not.
