I just posted this question on freebsd-questions, but, in reading
the stable mailing list again, I was wondering if this looked like
the same ahc problem. The system in question has *both* a Buslogic
PCI controller and a builtin Adaptec on the motherboard (unused
at the moment). e.g.:

It dies before it even mounts / with a kernel panic:
===================================================================
On booting a newly built kernel from freshly CV'supped -STABLE
source tree, I get this:
fatal trap 12: page fault while in kernel mode
0x24
supervisor read, page not present
:
panic: page fault
I was following the procedure in /usr/src/UPDATING:
make buildworld
make buildkernel KERNEL=YOUR_KERNEL_HERE
make installkernel KERNEL=YOUR_KERNEL_HERE
reboot (in single user) [1]
Breaks here ^
However, after booting old kernel, make installworld
done anyway:
make installworld
mergemaster
reboot
The make installworld didn't change anything. Same result with my
own custom kernel config file (includes ATM stuff) and the GENERIC
kernel (note, system is still running 4.1-RELEASE kernel after the
"make world").
So, I have built kernels directly with config/make depend/make/make
install, and, via make buildkernel. After my own kernels broke,
I tried GENERIC, with the same result every time.
uname -a doesn't tell you much since this is still the 4.1-RELEASE
kernel running:
4.1-RELEASE FreeBSD 4.1-RELEASE #0: Fri Jul 28 14:30:31 GMT 2000
