Dave Jones sent in a report about this with trinity too, I'm digging in

Hello,

My last known good kernel was from Dec 5 04:00 CST:

Linux version 4.4.0-120-generic (root@enigma.jons.org) (gcc version 
5.2.1 20151124 (Ubuntu 5.2.1-1ubuntu1~14.04) ) #201512050400 SMP Sat Dec 
5 03:54:25 CST 2015

I will check over the commits from then till now as well.
