Also, we do get a lot of tickets and sometimes things fall through the
cracks for which I apologize. If you feel you don't get enough
attention, you can always try to reach us on IRC libera.chat (channel
#ubuntu-kernel for the kernel team for example).

** Description changed:

+ [Impact]
+ 
  Using the Ubuntu image for Raspberry Pi from here:
  https://cdimage.ubuntu.com/releases/21.10/release/ubuntu-21.10-preinstalled-
  server-arm64+raspi.img.xz
  
  After installing the docker.io package, I cannot start a docker
  container. Example:
  
  $ sudo docker run --rm hello-world
  docker: Error response from daemon: failed to create endpoint pensive_greider 
on network bridge: failed to add the host (veth2102512) <=> sandbox 
(veth4fb66df) pair interfaces: operation not supported.
  
  Update for everyone searching for a workaround and finding this bug:
  
  sudo apt install linux-modules-extra-raspi
  
  You may want to indicate above that you are affected.
+ 
+ 
+ [Test Case]
+ 
+ $ apt install docker.io
+ $ docker run --rm hello-world
+ 
+ 
+ [Fix]
+ 
+ Add veth module to linux-modules.
+ 
+ 
+ [Where Problems Could Occur]
+ 
+ New modules might get loaded which could trigger kernel crashes.
