Documented in https://wiki.ubuntu.com/KarmicKoala/TechnicalOverview:
When creating LUKS encrypted partitions, some earlier versions of cryptsetup did not wipe out any pre-existing filesystem metadata on the partition. The current version of blkid used in the Ubuntu 9.10 RC will refuse to export a UUID for a partition containing more than one type of metadata signature. This means that encrypted disks may fail to be decrypted at boot time, possibly preventing the system from booting at all. Users of LUKS system-level disk encryption are advised to wait until the Ubuntu 9.10 final release before upgrading.
