Description of problem: The DFE-580TX (Rev A3) 4 port NIC exhibits selective instability when connected to different peers. Switches tend to be ok, but connecting other hardware will cause the connection to flutter. Inserting a switch inline, or dropping the link speed to 10FD cures the problem and allows the card to function at (the relevant) full speed. ethtool and mii-tool show no problems. running: # ethtool -s ethX autoneg off # ethtool -s ethX speed 10 to drop the link speed to 10BT full duplex stabilises the link. Version-Release number of selected component (if applicable): kernel-2.6.11-1.27_FC3 How reproducible: Every time. Kernel module used: /lib/modules/2.6.11-1.27_FC3/kernel/drivers/net/sundance.ko
Please retry with the latest errata kernel.
I have had to scrap this card along with a number of other semi-functional DLink products in order to get the system to work. I am therefore no longer in a position to test for fixes I'm afraid.
