Problems with cryptsetup and udev on feisty

[Josef Wolf]

Hello,

A couple of months ago, I installed the (at that time) brand-new feisty
and encryped several filesystems with luks,cipher=aes-cbc-essiv:sha256

All that worked for months like expected.

Until last week, when I made "apt-get update; apt-get upgrade".  Now I
can't "cryptsetup luksOpen" any more: after I enter the passphrase,
cryptsetup simply hangs for several minutes.  Finally I get an error
report:

  # cryptsetup luksOpen /dev/sda11 crypted
  key slot 0 unlocked.
  Rendezvous with udev timed out for 'crypted'; stat failed: No such file or directory
  Command successful.
  # 

Although it claims that the command was succesful, the filesystem don't
appear in /dev/mapper.


Googling for "rendezvous with udev timed" reveals that there are more
people with the same problem. AFAICS all of them use feisty/gutsy (or
something derived from that).  But unfortunately, nobody found a solution
by now.

Google also found two ubuntu bugzilla entries:

 - https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/117493
    this one is marked as a duplicate of #117502

 - https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/117502
    this one discusses a completely different topic (failure to type
    "YES" in uppercase when "cryptsetup luksFormat")

So #117493 is marked as duplicate by mistake!  Those are completely
unrelated problems.

Any ideas what caused this problem and how to solve it?
