>Description:
After compiling the SMP kernel and installing it, a reboot produces a list of
all the devices, then as soon as the second CPU is started the system locks up.
I cold-booted several times, once it actually started running /etc/rc but
locked about a half-second into it.
Rebooting the system under a uniprocessor kernel that I compiled works fine
without any detected problems.
>How-To-Repeat:
Compile the SMP kernel and restart, the kernel configuration file I used is
as follows:
#
# SMP-GENERIC -- Smp machine with WD/AHx/NCR/BTx family disks
#
# For more information read the handbook part System Administration ->
# Configuring the FreeBSD Kernel -> The Configuration File.
# The handbook is available in /usr/share/doc/handbook or online as
# latest version from the FreeBSD World Wide Web server
# <URL:http://www.FreeBSD.ORG/>;
#
# An exhaustive list of options and more detailed explanations of the
# device lines is present in the ./LINT configuration file. If you are
# in doubt as to the purpose or necessity of a line, check first in LINT.

>Fix:
Maybe bring back the option "SMP_TIMER_NC" to fix it? It looks like an
earlier SMP kernel did work on this hardware until the APIC_IO became
required.
Unfortunately, I only had about 4 hours to test on this machine - if 3.0
had run SMP we would have used this as a server, but since it won't the
system is consigned to use as an NT system and won't be generally available
in the future. Oh well.
