Here's the setup Compaq DL380 three i82555 chips. The first is on the mainboard and works great, the other two are on a compaq NC3134 controller, and worked under kernel 2.2.17 just fine. I upgraded to kernel 2.4.x and they stopped receiving data. Error generated: eth1: Transmit timeouted out: status e050 0x00 at 0/28 command 0001a000 Any ideas thanks! Derek
