Public bug reported:
Running Maverick on my Thinkpad W510. My wired network connection is
normally functional, but about once a week it stops transferring data.
This temporarily fixes the problem:
rmmod e1000e; modprobe e1000e
Wireless connectivity works fine even when the wired network is non-
functional. The lights on the wired network remain green even when non-
functional. Disconnecting and reconnecting the cable does not restore
functionality. I find no errors in the logs. The system thinks the
connection is functional, but no data is transferred.
It might be related to this bug:
Bug #619841 [REGRESSION] e1000e doesnt work on 2.6.35.
But the problem is intermittent.
