Hmmm, tried it and it works fine 
But one thing we fixed was mentioned AdBlock - it actually gets started now and when it starts, it tries to download lists you have setup and then merges them which poses quite some load on Omnia, so your problem might not be that related to kernel as to AdBlock slowing your network and resolver down as well as Omnia itself. It should stabilize itself after some time.
I pushed into hbk variant with reverted kernel update (building now, should be ready in about an hour), can @webknjaz or @julien113 confirm that that version works for them? This is only temporally solution, we need to get to the bottom of this, but it is hard to fix something we can’t reproduce
