Failed to setup dm-crypt

Hi, I've recently (within the last hour or so) updated my system and rebooted, only to find that my system cannot decrypt one of my partitions. cryptsetup comes back at me with:

Failed to setup dm-crypt key mapping for device /dev/md3.
Check that kernel supports serpent-xts-essiv:tgr192 cipher (check syslog for more info).

Unfortunately there doesn't seem to be anything in the syslog. The kernel has loaded the serpent_generic, serpent_sse2_x86_64, xts, and tgr192 modules.

Is it likely that I've missed something during the update? A missing kernel module or something changed in cryptsetup?

Thanks

Re: Failed to setup dm-crypt

Downgrading to cryptsetup version 1.6.4-1 has fixed the problem.

What's the process for filing a bug report?

Not a Sysadmin issue, moving to NC...
