I got this on both my build machine and my laptop (each i386 arch) this morning, though with different "<number>" values -- the build machine had 155; the laptop had 136. It's slightly easier for me to get the console output from the build machine (because I didn't have the serial console connected for my laptop during the last boot). Note that CURRENT ran OK (modulo LORs) up to today, so I should be able to produce a complete list of all source files that changed easily enough. (I'll get that list a bit later, after my laptop finishes coming back up cleanly.) The panic did not occur until rather late in the single-to-multi-user transition: /boot/kernel/acpi.ko text=0x53f4c data=0x25e0+0x186c syms=[0x4+0x8a20+0x4+0xbbc7] GDB: no debug ports present KDB: debugger backends: ddb KDB: current backend: ddb Copyright (c) 1992-2008 The FreeBSD Project.

I also have a local private mirror of the FreeBSD CVS repository handy, and am reasonably comfortable hacking sources, given a bit of direction. Peace, david -- David H. Wolfskill david_at_catwhisker.org I submit that "conspiracy" would be an appropriate collective noun for cats. See http://www.catwhisker.org/~david/publickey.gpg for my public key.
