Comment 3 for bug 1708399

according to the logs it might affect more docker than the kernel:

- docker is used on that system (at least since Aug 1st)
- but I cannot find that docker.io is used - which docker version is in use?
  dpkg log doesn't show me that docker.io got installed

- seems to be a docker issue that is causing a crash
 occurs multiple times per second

- the kernel log also shows some issues:
