Comment 7 for bug 561390

Same here, but sometimes everything works (about half the time):

I have /home under LVM:
/dev/cassini/cassini-home /home ext4 errors=remount-ro 0 1

The boot process (sometimes) hangs with the following message:
The disk drive for /home is not ready yet or not present.
Continue to wait; or Press S to skip mounting or M for manual recovery

I press M
# mount /home
# exit

and then the boot proceeds. See my mountall logs at comment 3
