Red Hat Bugzilla – Bug 241824
ethtool does not detect link with broadcom / tg3 network card
Last modified: 2007-11-30 17:12:05 EST
Description of problem:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot with no network cable attached
2. plug a network cable in
3. run ethtool
ethtool shows no link, the network card LED / Swith on the other end shows no
Link should be detected
running "service network restart" makes the network card recognize the link,
ethtool also shows it. The problem occurs with the onboard network card of a
Thinkpad X41 notebook. On fedora-test there was an e-mail about this, too:
There it affekts the F7 kernel, too. I did not test a F7 kernel.
This bug seems to have vanished, I did not have this probleme recently with F7,
so I guess it is fixed in FC6, too.
This is not fixed by F-7 on my system. The problem persists as previously reported.
Indeed, whenever I boot the particular workstation where my tg card is the gigabit ethernet device, I must
run ifup eth0 several times to get a connection--still.

There may also notice similiar beheaviour when you connect to a gigabit switch
with you gigabit nic but use a network cable that only connects the two cable
pairs that are used for fast ethernet. Then the link goes up after a little
timeout. With the HP switch I use it is around 15 seconds.
When I reported this bug, I also experienced this beheaviour with a fast
ethernet only setup, where I did not see this bug anymore.
