    My serial console logs only go back as far as April 25, but here
are the list of kernels I've attempted to boot.  These kernels may or
not have a matching world, since I haven't been able to always
successfully boot the new kernel prior to doing an installworld:


SUCCESSFUL BOOT:

FreeBSD 6.1-RC2 #151: Thu May  4 12:46:25 EDT 2006
FreeBSD 6.0-RELEASE-p6 #1: Sat Apr 15 19:59:37 EDT 2006


CRASH BEFORE REACHING INIT:

FreeBSD 6.1-RELEASE #203: Fri May 12 18:41:03 EDT 2006
FreeBSD 6.1-RELEASE #204: Thu May 25 14:05:40 EDT 2006
FreeBSD 6.1-RC2 #151: Thu May  4 12:46:25 EDT 2006
FreeBSD 6.1-PRERELEASE #1: Mon Apr  3 22:18:55 EDT 2006
FreeBSD 6.1-RELEASE-p1 #206: Thu Jun  1 03:30:38 EDT 2006
FreeBSD 6.1-RELEASE-p1 #207: Sat Jun  3 20:19:46 EDT 2006


    Notice how 6.1-RC2 #151 is on both lists.  I'm guessing there
isn't anything wrong with the kernels at all, and there is something
about the root filesystem or a file outside of the kernel (maybe a
kernel module, or a shared lib) that is somehow preventing post-6.0
kernels from seeing any filesystems.
