Public bug reported:
After the latest update, the Delete key on my USB keyboard stopped working.
The Delete key on my laptop keyboard also stopped working.
When I enter the BIOS, the Ctrl-Alt-Del key combination works fine.
The laptop reboots when I type on both the USB keyboard and the built-in
keyboard.
