I am seeing the same problem. Eventually the connection becomes so slow
that a reboot
is required to restore functionality.

I am using the generic kernel from 1.3.1 a Znyx 346 in a generic Intel

This happens whether or not the card is in "autosense" or "10baseT"
modes.
(I thought it was just me my card or my hub)
