This bug appears to have been reported against 'rawhide' during the Fedora 13 development cycle. Changing version to '13'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This happens when device is not available during lvm scan (missing module in initramfs or some kernel problem). If it is still reproducible, please reopen the bug and add more info (remove quiet option from kernel boot, if needed) and check if /dev/sda device is recognized before lvm scan. (I think this was just some temporary problem with dracut & initramfs, this works here without problem.)
