Title:
  Out of memory error when attempting to use Camera Module on RPi4

Status in linux-firmware-raspi2 package in Ubuntu:
  New

Bug description:
  Image: Ubuntu Core 20 armhf
  Devices: Raspberry Pi 4 2GB / 4GB / 8GB
  Camera Module v2.1

  Steps to reproduce:

  * Install the image
  * Edit /writable/system-data/var/lib/snapd/seed/config.txt to ensure the following lines are present:
  start_x=1
  gpu_mem=128
  * Reboot
  * sudo snap install checkbox --channel=uc20/stable --devmode
  * sudo checkbox.checkbox-cli
  * hit "/" then type "camera" to search for the camera tests
  * Press spacebar on the automated ones to select them, then enter
  * It will take you to another screen where you can deselect things, don't worry about it - just press "T" to start testing
  * It will ask you to confirm that you have a camera attached, just select yes, then "T" again to start testing

  
  The modules/cables in the lab have been moved to rpi2/rpi3 to confirm they are working
