Description of problem: I have 4x eth nic server, 1x wlan. One eth is used external interface ethext0, other (ethint0, ethint1, ethint2, wlan0) are bridged as bridge0. After update to Fedora 23, I'm getting kernel oopses. Version-Release number of selected component (if applicable): kernel-4.2.6-301.fc23.x86_64 How reproducible: Steps to Reproduce: 1. 2. 3.
