Hi I started getting this panic from Monday this week. The system is an old gigabyte dual pentium II. Scheduler is SCHED_BSD if that makes a difference so early on in the boot. A while back I got a similar panic (http://www.freebsd.org/cgi/getmsg.cgi?fetch=1649457+1655104+/usr/local/www/db/text/2004/freebsd-current/20040208.freebsd-current) Which, in summary, jhb thought was as a result of a missing MADT in the ACPI whatever. This problem in the above link went away and has now resurfaced after about 2 months. I do a fresh world and kernel from current sources about every two days.
