Bug Description
Linux 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Linux Mint 18 Sarah Cinnamon BETA
This hits at about the same time on every boot. I have three network interfaces on this thing and none of them work. DHCPDISCOVER times out regardless of which interface and a variety of drivers I've tried. I am assuming this kernel message has something to do with it but this is as far as I can go debugging it myself.

I can report that this no longer occurs when I remove the PCI-Ex1 wireless NIC, which as best I can tell is a Realtek 8192.
