Subject: 4.8.0-rc1: page allocation failure: order:3,
 mode:0x2084020(GFP_ATOMIC|__GFP_COMP)

L.S.,

Just tested 4.8.0-rc1, but i get the stack trace below, everything seems 
to continue fine afterwards though
(haven't tried to bisect it yet, hopefully someone has an insight 
without having to go through that :) )
My network config consists of a bridge and NAT.
