unfortunately i'm unable to reproduce the bug. i tested cryptsetup
2:1.1.0~rc2-1 and linux-image-2.6.31-1-amd64 2.6.31-1 on more than ten
different setups (luks on lvm, lvm on luks, luks on raid, luks on lvm on
raid, ...) and didn't see any problems.

maybe the issue is related to the 686 arch kernel, but i doubt that it
has any different configuration than the amd64 one.

does the issue happen all the time or only sometimes? the 'remove ioctl
failed: Device or resource busy' warning is a known issue and can be
ignored, but the message about temporary-cryptsetup-677 device shouldn't
occur.

'key slot 0 unlocked.' indicated that the device has been unlocked
successfully in the end, thus i don't understand why the boot breaks at
all.

it would be great if you could provide more information, in particular
the messages between 'key slot 0 unlocked' and busybox emergency shell.

greetings,
 jonas
