                AMD Ryzen "Freezing" Bug on GNU/Linux Systems
              
          
    Random "Freezing" with AMD Ryzen CPUs

It seems that numerous GNU/Linux users (including myself) have been having issues with the system randomly "freezing" during light usage. From journalctl output and anecdotal accounts, it is speculated that the AMD Ryzen CPUs do not support other C-states for power management very well (at least on GNU/Linux distributions), and the freezing may be resolved by limiting the C-state of the CPU.
Possible Solution

Limiting the C-state of the CPU can be done through the addition of the following kernel boot parameter.
processor.max_cstate=1

                Simple guide for setting up OTG modes on the Raspberry Pi Zero, the fast way!
              
          
    Setting up Pi Zero OTG - The quick way (No USB keyboard, mouse, HDMI monitor needed)

More details - http://blog.gbaman.info/?p=791
For this method, alongside your Pi Zero, MicroUSB cable and MicroSD card, only an additional computer is required, which can be running Windows (with Bonjour, iTunes or Quicktime installed), Mac OS or Linux (with Avahi Daemon installed, for example Ubuntu has it built in).

1. Flash Raspbian Jessie full or Raspbian Jessie Lite onto the SD card.

2. Once Raspbian is flashed, open up the boot partition (in Windows Explorer, Finder etc) and add to the bottom of the config.txt file dtoverlay=dwc2 on a new line, then save the file.

3. If using a recent release of Jessie (Dec 2016 onwards), then create a new file simply called ssh in the SD card as well. By default SSH i
