>Description:
I have an AST Pentium 75, 1,2 GB HD, 32 MB Ram.

I inserted 2 3Com EtherLink III PCI 4C590 (C) Network cards, and configured the machine as a gateway. I recompiled the kernel and put IPFW on.

The machine worked well for a while (including IPFW), but it crashed from time to time after a certain amount of Network traffic (varying from 10 to 100 MB). Sometimes, the machine froze completely, sometimes it kept working but dit not send or recieved any network pakkets.

I completely stripped down the kernel, excluding everyting that was not absolutely nessecary, but the problem remained. Then I changed 1 3Com card with a DEC DE200, and the problem got worse ! Now, it crashed after a few seconds or a few minutes.

At last, I removed both the 3C590 cards and used one DEC DE200 (ISA) and an 3C509 ISA. 

The problem seems to be gone. The system has sent over 1 GB of data without crashing.

So I suspect that there is a bug in the 3C590 PCI driver. Alas, I do not have the skills to debug and repair it. So I just report it.


Keep up the good work !
>How-To-Repeat:
Insert 2 3C590 PCI cards in an Pentium 75 running 2.2.5, and FTP some files to and from the machine.
>Fix:
I fully stripped down the kernel, but this didn't work. So I had to remove both the 3C590 Cards. This resolved the problem.
