Hi Pawel, Sorry about late response. We flashed EEPROM you sent us on X520-DA2 and ran an overnight stress test against couple different switch vendors and have not been able to repro.
This is closest as we can get as we don't have Juniper EX4500 in house. We'll continue to investigate with other switches. Just to make sure this is not an in-kernel only issue, could you please try our out-of-tree driver? http://sourceforge.net/projects/e1000/files/ixgbe%20stable/3.11.33/ At least that way we may be able to isolate the issue to in-kernel driver.
