You may try the attached patches on top of current -git. A complete dmesg
will be welcome. So will an 'ethtool -d eth0' if the device stops working.

You did not label the problem as a serious one. Does it means that the
driver automatically recovers ?

I'll add some ring and registers debug stuff tomorrow.
