I have an old box that I am using as my home firewall/NAT box for my residential cable ISP. It was running at or about 4.0.
I was using 2 xl interfaces (3com 3c509b's) and was very stable.
I have recently added another network at home, and wanted to add another interface to the box, so I added another 509b and the box became unstable. It would work, then hang, then work etc. The thing just rebooted itself a few minutes ago.
I installed 5.1-RELEASE on it for a couple of reasons, but was curious to see if I tickled a bug in the stack or driver by adding the 3rd nic. The box doesn't exhibit the exact same problems now, but still stops responding to network traffic once in a while. (i.e its still unstable, but the symptoms are different).
I am pretty sure the card I put in is OK - it came from a working system. The box is of an older vintage - Its a P133 with an Intel VX chipset on a gigabyte motherboard.
After a while last night, dmesg reported weird things, like just one garbled line.
The relevant bits from a working dmesg:

Any ideas?
Thanks! Tim
