Sources updated as of about 0330 hrs. US/Pacific today, from cvsup4.

Second time around, it booted OK, but when I issued sudo boot0cfg -s 1 ad0 && sudo reboot I saw the following panic (cut/pasted from serial console) -- I'll prepend a bit of the boot stuff for context: /boot/kernel/acpi.ko text=0x540f8 data=0x2640+0x186c syms=[0x4+0x8b40+0x4+0xbdcd] GDB: no debug ports present KDB: debugger backends: ddb KDB: current backend: ddb SMAP type=01 base=0000000000000000 len=000000000009fc00 SMAP type=02 base=000000000009fc00 len=0000000000000400 SMAP type=01 base=0000000000100000 len=000000003fee2800 SMAP type=02 base=000000003ffe2800 len=000000000001d800 SMAP type=02 base=00000000feda0000 len=0000000000060000 SMAP type=02 base=00000000ffb80000 len=0000000000480000 Copyright (c) 1992-2008 The FreeBSD Project.
