Bug description:
Running an up-to-date (as of Feb 25 2017) 16.04 / Unity on an old MSI
U160 netbook.
After a recent update to kernel 4.4.0-63 I have started getting frozen
login screens. The touchpad and keyboard are completely dead (before I
ever get to enter my password), and my only way out is to force
shutdown.
I can start GRUB on boot and go for an earlier version instead, but
everything past 4.4.0-62 freezes in the same fashion (that's what I'm
currently running as a temporary fix); a newer update to 4.4.0-64 has
not fixed the issue.
