After transferring about 100 megabytes over a gigabit link the transfer stopped and I have to reinit the link either by doing a ifconfig down/up or unplugging the network cable. The RxIntDelay is set to 0 like described in the docu. Playing with this Parameter only increases the amount of traffic to be send and the error occurs later. This happens also with the 7.4.35 and 7.5.5 driver from the intel side. The driver 5.7.6 from kernel 2.4.33.3 and the 6.1.16 from intel works very well on this hardware. Also other gigabit nics we use didn't have this problem. Is this issue already known? Is there any solution yet? Kind regards Wolfgang
