>Description:
After few minutes of FTP transfer (speed is about 3Mb/s), msk gets down - "ifconfig down/up" and cable unplugging/plugging don't help to recover it. There are continuously showing messages on console:

Tried on fresh STABLE (28 may), but the same behaviour is on 7.0-release and i386 kernel.
My system is ECS A740GM-M motherboard with Athlon 64 X2 4800+ (I've tried on other systems - there was the same symptoms...) and PCI-E D-Link DGE-560T network card. Here is hardware info:
dmesg message:

I'll be glad to assist and test any patches related to my problem... Thanks in advance!

Boot with D-Link DGE-560T and try to download something...
