kernel panic after fresh install of fc7-test3, then package updater

["mack sessoms" <mack sessoms gmail com>]

i get "no volume groups found", volume group "volgroup00" not found, then the kernel panic.  this has happened twice, once friday (99 updates available) and once today (125 updates available).  each time has been a fresh install from livecd, then updates via package updater.  i see this on a desktop system and on a laptop.
on a side note, i also noticed that clicking on the reboot button after the "install to hard drive" completes drops me to the desktop, never reboots.  I have to go up to the system menu, shutdown, restart.  anyone else seeing these?
