Same here, but please have in mind that the above solution only works
for the default entry in grub, if you want to be sure use
GRUB_CMDLINE_LINUX=i8042.nomux (=1 is obsolete according to docs) so it
also works for the older kernel.
But thanks for the solution whover came up with it the first
I had the same problem (keyboard not working, touchpad working) for a
6.x kernel. The workaround from Johannes and Bernd worked for me, though
I only used "quiet splash i8042.nomux=1" and did not test the additional
"i8042.reset".
System: Fujitsu Lifebook 7U15A1, Ubuntu 22.04.3 LTS, Kernel

sudo vi /etc/default/grub
# --
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux=1"
# --

Another user in the Ask Ubuntu thread reports, that the problem may be
related to a false switch to tablet mode. I confirm the output of my
device of "cat /sys/class/dmi/id/chassis_type" is "10". In addition: The
E5410 is not a tablet nor a convertible, so it should not switch to
tablet mode.
