The patches added to 2.2.16:

1. 3Com Drivers (left from 2.2.15)
2. Willy Tarreau's kmsgdump patch

3. Forgot to enable generic EIDE driver so I could use DMA on my hard
drive (though it doesn't like the chipset I think 2.4.x has some changes
though not sure).

I ran the same source code consecutive times without crashing in the loop.
I heard from someone that in 2.2.15 there was a bug in the networking code
somewhere that caused something like this. I'm not sure.

What I am sure is that it appears to be fixed :))

Keep it up guys!
