FC3 "INIT: Id 1 respawning too fast..." message on boot

[Jeff Camp <jcamp2@xxxxxxx>]

When my newly installed FC3 (2.6.9-1.667) system boots, everything looks 
good and I get a login prompt.  When I enter the user name it comes back 
with the "INIT: Id 1 respawning too fast, disabled for 5 min".  Afer a 
minute or so it gives the same message with "Id 2, 3.."

Any suggestions where I should start?
