What is very strange is that all devices are freezing exactly 4h after boot. We have had this exact same issue on more than 20 devices (over 100), with parts from different batches, and all did freeze exactly 4h after boot (but it's not reproducible, it won't freeze every day). Some devices are playing MPV videos, while other run chromium. They are running non-stop, but are all rebooting daily at 05h05. Looks like it might be related to https://lkml.org/lkml/2015/6/11/787 That seem to have been fixed and backported already https://lkml.org/lkml/2015/10/17/259 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-64-generic 4.4.0-64.85 ProcVersionSignature: Ubuntu 4.4.0-64.85-generic 4.4.44 Uname: Linux 4.4.0-64-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.4 Architecture: amd64 Date: Mon Feb 27 21:06:44 2017 InstallationDate: Installed on 2016-06-08 (264 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 8087:0a2b Intel Corp.
