Similar symptoms on Acer Aspire E5-521 - no touchpad or USB mouse, no
wifi, only generic graphics driver. Reverting to 4.4.0-42-generic is
effective as a workaround.

Fix suggested by Matti Laakso (comment #17) restores all but wifi:

apt install linux-image-extra-4.4.0-43

Running "dkms status" shows that the Broadcom Wifi driver (bcmwl) failed
to build for 4.4.0-43-generic. To fix this as well:

apt install linux-headers-4.4.0-43-generic

Driver should build (for 4.4.0-43-generic) and function normally again
on reboot.
