Subject: BUG: hard lockups on docker operations

Hello kernel hackers,

I'm getting hard lockups with kernel 4.4.5 (at least 4.4.3 and 4.4.4
also). This is a docker hypervisor machine with overlayfs and 3ware
RAID.

They usually happen when I do something with docker, here when I ran
poweroff in a container (those are all VM-like containers which run /sbin/init
inside).

Oops follows:

NMI watchdog: Watchdog detected hard LOCKUP on cpu 4

If more info is needed, I'll happily provide it.
