Known Issues

1. There are several stability issues regarding the camera driver.  Rebooting the Maivin will usually clear these issues.  If the camera does not work after two consecutive reboots, please enter a ticket.  Issues with the camera driver are currently under investigation and include:
   1. The webpage shows black camera feed
   2. The webpage camera feed is upside down
   3. The docker does not start with error:  "/dev/video0 is not a video capture device"
