Public bug reported:
I swapped from the r8169 driver to r8168 for stability, but as time has
passed stability has suffered here too. Now it's unreliable.

And so on. Occurs when the network interface is busy with multiple
connections. With a single busy connection it seems to work fine.
Multiple connections work fine when things are not busy.

I can't find an updated Linux driver to test. I've downloaded an updated
WinXP driver and will try it with ndiswrapper, and see if that makes any
