My machine has locked up solid and rebooted a few times lately; the
most recent time I managed to get this from the console (copied by
hand - I believe it's accurate, but no guarantees):

============================================================
Can anyone translate? Is one of my disks failing? If so, which one?
The lockups do appear correlated with heavy disk activity.
Below, I've included the current /var/run/dmesg.boot and kernel
configuration files. These crashes have left no trace (that I can
find) in any of the log files.
I'm running Stable from last Friday:

The machine is a Dell with an Adaptec 2940, one Quantum Viking hard
drive, and one Fujitsu (external drive in Sun packaging) hard drive.
Thanks for any light you can shed on this -- and guidance you can
offer.

# IPFIREWALL enables support for IP firewall construction, in
# conjunction with the `ipfw' program. IPFIREWALL_VERBOSE sends
# logged packets to the system logger. IPFIREWALL_VERBOSE_LIMIT
# limits the number of times a matching entry can be logged.
#
# WARNING: IPFIREWALL defaults to a policy of deny ip from any to any
# and if you do not add other rules during startup to allow access,
# YOU WILL LOCK YOURSELF OUT. It is suggested that you set firewall=open
# in /etc/rc.conf when first enabling this feature, then refining the
# firewall rules in /etc/rc.firewall after you've tested that the new kernel
# feature works properly.
#
# IPFIREWALL_DEFAULT_TO_ACCEPT causes the default rule (at boot) to
# allow everything. Use with care, if a cracker can crash your
# firewall machine, they can get to your protected machines. However,
# if you are using it as an as-needed filter for specific problems as
# they arise, then this may be for you. Changing the default to 'allow'
# means that you won't get stuck if the kernel and /sbin/ipfw binary get
# out of sync.
#
# IPDIVERT enables the divert IP sockets, used by ``ipfw divert''

# IPFILTER enables Darren Reed's ipfilter package.
