>Description:
I am seeing this consistently when I tried to do a build/installworld/kernel with daily sources from the master tree:

  http://www.mediafire.com/imageview.php?quickkey=qmhizdtnhyo&thumb=4

The system boots fine single-user.  Problem is repeatable with both
my kernel AND GENERIC. (My config file at end of this msg.)

Attempting to enter multi-user causes the problem.  This
occurs whether or not anything is enabled in /etc/rc.conf.

Falling back to my 6-18-2010 system image makes everything right again.

MOBO is an Intel D946GZIS with a single SATA drive and one additional
3Com 3c905 NIC in addition to the onboard Intel NIC.
