Public bug reported:

When using the 4.4.0-9-generic the splash screen that asks for my
encryption password don't register any keypresses. If i force the laptop
to shut down and boot again the screen doesn't even show, it's just
purple. But then I can enter my password and hit enter and it will
unlock and bring me to the Ubuntu login screen.

When shutting down it hangs on "A stop job is running..." (/dev/dm-0 i
think it was) until it times out (90 sec).

If I switch back to the 4.4.0-8-generic kernel it all works just fine,
boot goes to splash screen, I can type in my encryption password, and it
also shuts down without waiting for 90 secs.
