I had the same problem with zfs too.
Changed :
CONFIG_RETPOLINE=y
to
CONFIG_RETPOLINE=n
in
/boot/config-4.4.0-116-generic
and reinstalled the nvidia/zfs kernel modules.
To me it seems that the config file shipped with the kernel is not
matching the version used for compiling.

Title:
4.4.0-116 Kernel update on 2/21 breaks Nvidia drivers (on 14.04 and
16.04) by an insufficient compiler!

Bug description:
Running fine with nvidia-384 until this kernel update came along.
When booted into the new kernel, got super low resolution and nvidia-
settings was missing most of its functionality - could not change
resolution.
Rebooted into 4.4.0-112 kernel and all was well.
The root cause of the problem has been found to be installing the -116
kernel without a sufficiently updated version of gcc. In my case, my
system received the gcc update AFTER the kernel update.
Uninstalling the -116 kernel and reinstalling it with the updated
version of gcc solved the problem for me.
