Recent lockup in `kickstart'

I've recently updated two different uniprocessor machines to HEAD.
They both lock up before 'kickstart' is printed in multiuser mode.
A kernel from Nov 8 15:10:08 EET 2004 doesn't lock, which is what
I am using now to post this.

I am trying to build a kernel from Nov 9 02:00 UTC, right after a pair
of commits by Dag-Erling Smorgrav:

2004.11.09.00.55.23 sys/resource.h 1.26 des
2004.11.09.01.33.58 sys/resource.h 1.27 des

to see if that kernel works.

When I break into the debugger during the lockup of the kernel, the only
lock held is Giant at kern_intr.c:545, if that helps a bit in finding
out the source of the problem.
