Does this still occur if you powerdown and then try again?
This is a known problem with the warm reboot. See PR 7174 at
If this occurs on your system when trying to boot immediately after a
power on, please let me know (or submit a followup to the above
mentioned PR) and I will move it up on my priority list.
