The disks should have spun up long before a reset gets
issued.

It is the firmware (and maybe a bootstrap) that boots a CD.
Once control is handed over to the FreeBSD kernel, then the
kernel has to be able to talk to the disks.  It is the
FreeBSD 7
kernel that is having the problem.

No, it is "device aptic".  It was in 6 but removed
from 7.  I had to add
aptic to get my nforce4-ultra board to boot 7.  Given that 6
runs on
Shaun's machine and 7 doesn't, adding aptic is a useful
thing to try.

Not necessarily.  It ultimately depends on what the system
is engineered
to do during a soft reboot.  The disks themselves may be
powering down
briefly, may take a long time to initialise, or maybe
there's a bug in
the drive firmware.

My personal guess is that it's a BIOS bug.

Again, not necessarily.  I think I've provided enough
evidence of where
BIOS settings can affect FreeBSD's behaviour when it comes
to disk
controllers.  My RAID question was one such example.

There is no "aptic" device on RELENG_6.  I just
did a grep -ri "aptic"
/usr/src on our RELENG_6 box and found absolutely no trace
of said
device.  You are thinking of "apic".
