I've tried recreating this bug with Karmic and was unable to, given the
information you've provided. Please either a) upgrade and test or b)
increase the verbosity of the steps to recreate it so we can try again.

Please feel free to report any other bugs you may find.


But it looked like you reinstalled the grub headers to /dev/sda7, which caused you partition to become corrupt.

Title:
  LUKS partition corrupted

Status in “cryptsetup” package in Ubuntu:
  Incomplete

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.
