Title:
Keyboard and Touchpad do not work after suspend/resume
Status in linux package in Ubuntu:
Confirmed
Bug description:
My laptop is a Toshiba Satellite C850D with updated 18.04 installed.
When resuming from suspend, I have no keyboard and touchpad.
dmesg shows "i8042: Can't reactivate KBD port"
This looks like a recurring problem, and is just like these:

Here's the dmesg output from before and after suspending.

This post also talks about this bit failing for a lot of people!

Some of the function keys work, such as changing the screen
brightness, but the key (fn+F5) does not turn the touchpad back on. I
have not yet tried any of the suggested options, as results have been
mixed, but I will.
