Hi all,

I'm having problems with a 10GbE Intel X520-SR2 interface. After a running time, the interface does not send or receive more data. I am obliged to make a down and up the interface for it to return to work. Have changed the interface, optical cords, optical modules and problem continues.

Could be an issue with the ixgbe driver?

Thanks
