tg3 module resets repeatedly on 2.6.17-9

[Mikael Nilsson]

Since 2.6.17-9, I've observed the following:

This happens every few minutes, and is extremely annoying. I have never seen this before...

Seems to be related to this - and also happens on earlier kernels, I now see.

Yes, I'm behind a router (with NAT), and yes, doing bittorrent.

Have you tried the suggestion in the thread?

ethtool -k eth0 tso off

[Mikael Nilsson (mini)]

that command does seem to help a bit, but it still resets regularly.

Hardy Heron 8.04 was recently released. It would be helpful if you could test the new release and verify if this is still an issue - http://www.ubuntu.com/testing . You should be able to test your bug using the LiveCD. Please let us know your results. Thanks.
