Argh! I'll work on this tomorrow. Actually I'm not sure this was ever tested since I was more concerned with making sure "a" prints a "a" in non-us keyboards, than verifying timeout was still working ... I confirm I can reproduce as well. A workaround is to use the following property in /etc/default/grub and rebuild the menu: -------- 8< ---------------- 8< ---------------- 8< ---------------- 8< -------- GRUB_TIMEOUT_STYLE="countdown" -------- 8< ---------------- 8< ---------------- 8< ---------------- 8< -------- This was fixed Upstream by:

at_keyboard: Fix unreliable key presses
This patch fixes an issue that prevented the at_keyboard module to work
(for me). The cause was a bad/wrong return value in the
grub_at_keyboard_getkey() function in grub-core/term/at_keyboard.c file
at line 237. My symptoms were to have an unresponsive keyboard. Keys
needed to be pressed 10x and more to effectively be printed sometimes
generating multiple key presses (after 1 or 2 sec of no printing). It
was very problematic when typing passphrase in early stage (with
GRUB_ENABLE_CRYPTODISK). When switched to "console" terminal input
keyboard worked perfectly. It also worked great with the GRUB 2.02
packaged by Debian (2.02+dfsg1-20). It was not an output issue but an
input one.
I've managed to analyze the issue and found that it came from the commit
216950a4e (at_keyboard: Split protocol from controller code.). Three
lines where moved from the fetch_key() function in
grub-core/term/at_keyboard.c file to the beginning of
grub_at_keyboard_getkey() function (same file). However, returning -1
made sense when it happened in fetch_key() function but not anymore in
grub_at_keyboard_getkey() function which should return GRUB_TERM_NO_KEY.
I think it was just an incomplete cut-paste missing a small manual
correction. Let's fix it.

Countdown with 2.02-114.el8.x86_64
I can confirm it works with 2.02-114.el8.x86_64 compared to 2.02-106.el8.x86_64. Screenshots attached. Procedure: 1. Configure at_keyboard with FR keyboard and reboot (https://access.redhat.com/solutions/5624811) --> no countdown 2. Update to 2.02-114.el8.x86_64 and execute "grub2-install" and reboot --> 5 seconds countdown Verified: tested based on comment 12 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
