Sat 22 Apr 2023 12:44:00 PM UTC, original submission:   This has been happening for over 5 years: https://ticket.coreboot.org/issues/141 On EliteBooks with Coreboot+GRUB, GRUB hangs infinitely on the menu screen. When using Coreboot+SeaBIOS to load GRUB from an MBR hard drive, GRUB works fine. I fixed this by implementing a 200 ms timeout in keyboard_controller_wait_until_ready. This patch is now automatically applied in Libreboot. Keyboard works correctly now, and GRUB no longer hangs.	Riku Viitanen <riku_v>
