[vortex] Strange 3c905c problem [rolf@noxs.nl]

[Rolf]

I run a server with a Asus A7V266-e motherboard and 3c905c network card 
and kernel 2.4.18.
Everything works fine when using a 10Mbs connection. When I switch to a 
100Mbs connection traffic from the server works fine, but as soon as I try 
to download something to the server the network connection stops 
completely (no traffic in or out). When I stop the download the connection 
starts functioning again after a few seconds.
The network connection works fine when I use an other NIC.

Any suggestions??

Thanks Rolf Theunissen
