I've seen some "hang fixes" on 03.06.2015, but I'm not sure if they are related to this issue. This problem is pretty annoying: We have a performance penalty for all network cards right now as the buffer size of the core network stack had to be decreased to 4096 bytes again on our side. (https://www.marc.info/?l=linux-netdev&m=142131668206333) Better than no e1000e network connectivity though. The initial report on this issue was on 14.01.2015: https://www.marc.info/?l=linux-netdev&m=142124954120315 Best regards, Thomas
