[I'm at least a week behind on mail -- just got back in town over the weekend -- so if this has been covered, I apologize for the duplication.] I've been tracking both RELENG_6 & HEAD on my laptop on a daily basis for a while; I also try to track them on a weekly basis on my desktop at work. On 25 March, I had no problem doing that; on 02 April, RELENG_6 was fine, but HEAD hit a panic during the transition from single-user mode to multi-user mode -- but only on my work desktop (my laptop doesn't exhibit the problem at all). I *suspect* -- based on the sequence of events -- that the initial panic may well be associated with a NIC, and that the kbd driver gets a secondary panic; regardless of what I suspect, the keyboard isn't usable once the panic message spits out, but a serial console does work. The nice thing is that the panic appears to be 100% reproducible; here is a cut/paste from the serial console: /boot/kernel/acpi.ko text=0x43b18 data=0x24a0+0xff0 syms=[0x4+0x7c10+0x4+0xa8bb] GDB: no debug ports present KDB: debugger backends: ddb KDB: current backend: ddb Copyright (c) 1992-2006 The FreeBSD Project.

I can make the dump available, I expect, should that be useful. I'm not sure how soon I will be able to do much with my email backlog (which was at around 1K messages), so I've set Reply-To to add an address for which I'll be monitoring mail more closely during the workday. Oh: the local mirror from which /usr/src was updated had last been updated a bit before 0400 hrs US/Pacific on 02 Apr 2006. Peace, david -- David H.
