Comment 78 for bug 279102

Problem still present here.
Tried 2.6.32-22 and 2.6.34 (no rc) from PPA
Linux ally 2.6.34-020634-generic #020634 SMP Mon May 17 19:27:49 UTC 2010 x86_64 GNU/Linux

It is most definitely network load related.
I use mythtv. It plays the live tv, but as soon as I go to view the program guide, the ethernet interface goes up and down.

Some way needs to be found to recover from overload more gracefully.
