grub accepts only one key press in total

grub2 (Ubuntu)

Bug Description

When grub start, I can press exactly one key, then all other key presses are ignored. I cannot tell if grub crashes or not.

This one keypress could be RETURN, then normal boot continues. It could be ARROW DOWN, then the second line in the grub menu is selected.

But from then on, all further key presses are ignored, be they RETURN, ARROW UP/DOWN, even CTRL+ALT+DEL.

This breaks the selection of MEMTEST and other grub entries but the first.

Note that I'm using a regular USB keyboard.

Same problem. It happens when I installed Ubuntu 18.04.1 over Windows 10 to make it dual boot. Everything works fine, until you press enter on the main grub but as soon as you press down key to select other option, it Grub screen freezes and you have to press force shutdown button from CPU.

Did anyone found solution for this?
