Subject: Bug in 4.5.0: hard lockups on docker operations

Hello kernel hackers,

I'm still getting hard lockups on my docker machine with overlayfs and
3ware RAID with linux 4.5.0. They look a bit different though.
It would be great if someone could look into it.
Kernel messages follow:

NMI watchdog: Watchdog detected hard LOCKUP on cpu 6
Kernel panic - not syncing: Hard LOCKUP

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