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.
