Does it have to be 3.1.0-rc3 or is 3.0.1 ok as well ?

Almost any release may exhibit the bug. The attached patch (#0003)
should be a better candidate as an official fix though.

ok, good news: I did not experience any freeze anymore even though I 
transfered 60 GB. And I applied both of your patches and 

-                   if (status & RxFOVF) {
-                           rtl8169_schedule_work(dev, rtl8169_reset_task);
-                           dev->stats.rx_fifo_errors++;
-                   }

If so, I have another bad news: 3.0.1 still crashes with this patch.
It took me a lot longer to crash it but eventually it did happen.
Not sure why it took longer, I guess I didn't generate enough throughput.

It sure sucks from a user experience viewpoint but it is not _that_ bad.

I disagree - I actually lose data because I mount my data and backups with 
iSCSI and exactly then it crashes.

Are the symptoms in any way different or do you still notice more-or-less
periodic link-up messages and no real network traffic ?

dmesg looks like this:

so yes but what do you mean with "no real network traffic"? I still get
100 MB/s.
