Red Hat Bugzilla – Bug 165026
DFE-580TX cannot hold up 100BT link with some peers
Last modified: 2007-11-30 17:11:11 EST
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.
# 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 module used:
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.
