Hi!

Using a home grown client/server app, I have been able to easily crash
Linux. The application is a
simple udp sender/receiver. The udp receiver runs on a Linux machine with a
3c905b Ethernet
card which uses the latest version of the 3c59x.o module (v0.99L), and the
kernel is 2.2.12-20. By sending the Linux machine a 100MB file as fast as
the sender can send it on a 100Mbps network, the Linux machine responds by
freezing up completely with a console message that states:

I have exactly the same here on 2.2.13 kernels... so it really is a nast
one... nice one to boot out 100 mbit boxes wich are using this card a lot.
I'll be testing with 2.2.14 wich is just released but i dont think they
altered that code there. I am using 3c590 ....

Sad.

If its fixed in 2.2.14 i'll do another post .-)

Bey,
Raymond.
