I've discovered a problem after upgrading to 3.10.0-957.1.3 kernel. We have a DHCP server up and running on our Intel NUC any a Wireless AP connected.
As soon as I connect with my PC it works perfectly. But if i start streaming NETFLIX i do get a "eno1: Detected Hardware Unit Hang"
Code: Select all

Netflix, NRK (Norwegian TV), Ookla speedtest
Youtube works perfectly fine, doing iPerf3 to another DHCP unit on the network gets about 700-800 throughoutput both ways (on cable). Also local speedtest works superb. But if i use a ethernet connected Chromecast device and start netflix it crashes. Youtube still works .
So seems like heavy load as a "client" on this DHCP server makes it die. But not youtube
Any idea on what might be "f...d"? Happend during the latest firmware upgrade.
I can do
