freebsd stable - Jan 2007 - Fatal Trap 12 in 6.2-PRERELEASE

I rebuilt and installed the kernel and world, and now when I
try to boot the system it fails with a Fatal Trap 12: page
fault while in kernel mode, with current process of 594 (ntpd).

Since it always fails, I can't do any of the checks in FAQ Advance Topics,
or other checks.

Other than reinstall, is there anything I can do?

FWIW, this is on a Toshiba satellite laptop.

Thanks

Try booting the old kernel, which is called kernel.old. See the
bottom of this page for how it is done:

I dont' have the thread subject handy, but I remember something here a 
week or two ago about a commit that screwed things up and the symptom was 
that the first thing to hit the network (many time ntpd) caused the panic.

Did you also cvsup before you rebuilt the kernel?  If so, there's a good 
chance you're hitting a known bug.
