[31016.239899] Kernel panic - not syncing: Fatal exception in interrupt
[31016.239899] Kernel Offset: disabled
We believe this appeared in the last 1-2mo of releases, since this started
happening after we did a `apt-get upgrade` on our machines after a bit of a
pause. These are EC2 m4.xlarge servers running Ubuntu 16.04.1. They are
Kubernetes minions, so I assume docker is likely the trigger.
Unfortunately there aren't really any interesting logs in journalctl
from the previous boot prior to the panic.
Let me know what I can do to debug further.
