F10 Post install encrypt partition issue

Hello,

I installed F10 last night. Install went file. The machine was previously
running F9 with encrypted /root and /home. For the install on F10 did an
install, not upgrade, and formatted /root. Left /home alone.

During the boot process I get prompted for the passphrase to unlock the
encryption for /root. Once the system gets to the interactive boot process
and does the check disks routine I do not get prompted to enter a passphrase
to allow access to  the encrypted /home.

I get the following error then it drops me to a maintenance prompt.

Checking filesystems
/dev/mapper/luks-ce0ce45d5-c705-4fde-8f7d-a17172c39aae: clean, 125896/655370

/dev/mapper/luks-d8590a73-6fd0-46e5-8135-3ad739f58f6c:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2 filesystem
(and not swap or ufs or something else), then the superblock is corrupt, and
you might try running e2fsck with an anternate superblock: e2fsck -b 8193

/boot: clean 36/26104 files, 17648/104388 blocks

I've verified through in maintenance mode that /etc/crypttab looks fine and
the same with /etc/fstab. I can unlock my encrypted /home by running
cryptsetup luksOpen /dev/mapper/VGSys-LVHome
luks-d8590a73-6fd0-46e5-8135-3ad739f58f6c and providing the passphrase. I
then can mount /home. So I know things with that are good and the data is
there. The problem is that during bootup it just doesn't prompt for the
passphrase to unlock /home.

>From what I can tell /etc/rc.sysinit is responsible for mount partitions and
in the case of encrypted volumes asking for the passphrase. I'm wondering if
this is a bug.

Any help is appreciated.

Thanks,
Jason
