Extract from /var/log/messages
A new occurance toady caused the network to again stop working. I will attach an

Note: in the log, at 12:00:42 the network was stopped manually by root.
Also, not sure what entry at 12:01:38 - 'switching to MII media' means.
can you try and repeat this on the errata kernel ? 2.6.9 is quite old.
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem. Please update to this new kernel, and
report whether or not it fixes your problem.
If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.
Closed due to lack of response. Please re-open when the requested test
results are available...thanks!
