I have tried to connect 2 peers to each other, then only one peer crashes. By bisect, this commit looks causes this issue. commit d8da0b5d64d58f7775a94bcf12dda50f13a76f22 Author: Cedric Izoard Date: Wed Dec 7 09:59:00 2016 +0000 mac80211: Ensure enough headroom when forwarding mesh pkt When a buffer is duplicated during MESH packet forwarding, this patch ensures that the new buffer has enough headroom. I do not have any crash log because the computer was fully uncontrollable. Regards, Masashi Honma.
