Hello,
            I have a 3c905C and get following errors under medium 
network loads.
The hub, network, and all other stuff is quite good. Also on same 
machine Win2K gave
no problems. When the error occurs, I get transfer speeds of 0.43 Kbps. 
I never experienced the
same with Win2K.

*******************Keeps repeating..

After some time the network becomes unusable. The problem is always 
reproducible.
I run Kernel-2.4.6-2 on RH7.1 (From Rawhide). Is there any update for 
the 3c59x driver for 2.4.x kernels?
