Title:
System freeze after in6_dev_finish_destroy errors
Status in linux package in Ubuntu:
Incomplete
Bug description:
After the upgrade to the `4.4.0-83-generic #106~14.04.1-Ubuntu` kernel
we are seeing system hangs with the following logs. Prior to this
upgrade there were no crashes or kernel traces of this sort. We have
ruled out physical hardware issues by moving the VM to another
physical host.
In the logs there's reference to docker instances on the host. This
results in veth devices being brought up and torn down frequently,
which is likely related.
As a possible workaround we have disabled IPv6 for now.
```
