spencer at oldbox:~[501]> grep REL standard-supfile
*default release=cvs tag=RELENG_5_3

Aaargh.  I upgraded the box and didn't change my src supfile.

Fixed now; cvsup to get 5.4 source, new kernel build.  Result:

FreeBSD oldbox 5.4-RELEASE-p18 FreeBSD 5.4-RELEASE-p18 #0: Mon Sep 18 08:39:41 CDT 2006     root at oldbox:/usr/obj/usr/src/sys/kernel.2006Sep18  i386
