Description Artem S. Tashkinov 2007-10-20 15:30:01 UTC 
The issue is well described here: http://lkml.org/lkml/2007/7/2/52

For the last two minutes I've got this:

eth0: link up.
eth0: link down.
eth0: link up.
eth0: link down.
eth0: link up.
eth0: link down.
eth0: link up.
eth0: link down.
eth0: link up.
eth0: link down.
eth0: link up.
eth0: link down.
eth0: link up.

It's very irritating. If I connect the same cable into Intel Pro 100 Mbit NIC then there are no disconnects.

# ethtool eth0

Closing for a while since I have primarily switched to a different NIC.

Also this bug seems like a duplicate of bug 8354.
