[Soekris] NET4501 Instability

Hi List,

I have a NET4501 running OpenBSD 3.7 that I am using as a firewall and
wireless access point (Atheros minipci 5354 based card).  It works
well except for one nagging issue - it spontaneously reboots every now
and then.

At first, the problem manifested itself as conflicting IP addresses on
my network.  The Soekris box is running ISC DHCPd and the lease file
is stored in a memory filesystem.  With each reboot, it would lose its
record of leases and would dole out duplicate addresses.

I began suspecting that the box might be having problems when my
internet connection would suddenly fail and I'd connect to the box to
see it at the "boot>" prompt.  I'm actually not clear on why it
stopped there, because it should have automatically come all the way
up - it usually does.

Regardless, this rebooting is becoming a bit of a hassle and I'm not
sure where to look.  The logs are obviously temporary (CF is the
primary boot drive) and do not survive a reboot. I could log to a
syslog server, but I suspect the failure happens so quickly that it
wouldn't have time to get off a message. Furthermore, upon leaving a
console connection open, I see effectively nothing - other than the
fact that it rebooted:

It's done this twice today.  Any ideas?
