This is a Fedora issue, not LVM, and you might try the Fedora IRC chat, but...

Have you tried running mkinitrd again since you got the system booted?
Since you just upgraded, mkinitrd could have screwed up since drivers
and device names may have changed from 13 to 15.  I even had this problem
with CentOS, 5.5 -> 5.6 mkinitrd had to be run again (after booting from
older kernel).
