Description Jaroslav Fojtik 2013-05-07 07:32:16 UTC 
The ethernet driver is rock stable on 10M/100M modes. 

1G mode causes ethernet device freezing. But everything else seems to continue working. I am not alone who is facing this problem.

Here is another desperate guy:

It looks like drop packet count starts to increase and the device is not able to receive packet. All packets are dropped.

It seems to be different kind of bug than this one:
