======================================================================== WARNING! You seem to be running flashrom on a laptop. Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing.

This is what you are experiencing.
After this the keyboard and touchpad stops working. Also one of the thermal sensors stops working too.
This, as well as...

...this points to a crashed embedded controller.
Shutting down and removing power cable and battery resets the condition so "sudo flashrom" just disables keyboard/touchpad.
Because this resets the embedded controller.
I read some abut making support for a laptop but it seemed a bit complicated for me.
If you have a vendor BIOS update, the magic to code needed to have the EC cooperate is included within that update. Do you have a link?
