When using the VM from https://github.com/openshift-evangelists/vagrant-origin with a new kernel, at some point kworker takes 100% of cpu and it becomes unusable.

Workaround from moby/moby#3280:

Edit /etc/sysconfig/docker-storage:

DOCKER_STORAGE_OPTIONS=--storage-opt dm.blkdiscard=false

And reboot (to restart Docker).
