I'm using sys-fs/cryptsetup-1.1.1_rc1 since 02.05.2010 and didn't have
any issues.
Please decrypt your partition from the command line, so we can see if it
is a cryptsetup/luks/kernel problem or a pam_mount problem.Cmdline should something like: $ sudo cryptsetup -d /etc/security/verysekrit.key luksOpen /dev/mapper/VG01-crypthome myhome Which should create /dev/mapper/myhome.
