A Cry for help (OpenBSD 2.7 firewall based on I810e chipset crashing) Dmesg and all hardware details included. (Long Post)

["Collin B. McClendon" <Collin@macrosys.com>]

Sorry for the long post, this is really important at least to me, since its
a big deal to have the firewall go down...I'd appreciate any help at all.
Here is the error message, this is on the vga console after a complete
network/serial port lockup:

wd0c pciide0:0:0 timeout
c_bcount:8192
c_skip:0

dc0:watch dog timeout 

I can't login or anything. I didn't find a core dump. I rebooted. Uptime was
21 days. The machine filters traffic for a web server behind it on a private
subnet. 125,000 page a 
day are viewed. The bandwith stats right now as of 2:00pm EST are

Max In: 2051.4 kb/s (2.1%) Average In: 166.7 kb/s (0.2%) Current In: 96.5
kb/s (0.1%) 
Max Out: 763.6 kb/s (0.8%) Average Out: 50.0 kb/s (0.0%) Current Out: 31.6
kb/s (0.0%) 

I have an Intel i810e motherboard with onboard audio and lan. It has a 2nd
ethernet card which is a KNE110TX. 
This is the digital chipset, dc0 driver used. The onboard lan is an intel
etherexpress pro /100 embedded. Other hardware is a seagate ata 66 drive,
model ST310212A. I also have a floppy drive from teach in the machine. This
model of harddrive has been reliable to the maximum in every machine I have
used so far. This goes for the ethernet card as well. The ram is from
Crucial,
and is pc100 unbuffered.  Part # CT16M64S4D8E.

Here is a dmesg:

WARNING: / was not properly unmounted

I recompiled the kernel to up the files and sockets available here are the
lines I added:
option NMBCLUSTERS=8192
option NKMEMCLUSTERS=8192
option MAX_KMAP=120
option MAX_KMAPENT=6000

I think that's all I can say about this, I can include my ipf and ipnat
rules if needed. 
I'd appreciate any help you can give,
Collin
