Here I had exactly the same problem on my ancient laptop running 
6.1-STABLE. I solved the problem by removing the kbdmux device from my 
kernel configuration. This laptop uses the atkbd driver for the keyboard.

I also verified this on a Pentium 4, also using an AT keyboard: if 
kbdmux is in the kernel configuration the problem occurs, if it is not, 
the system behaves normally when using "shutdown -h now".

So I advise to delete or comment the line:

device          kbdmux          # keyboard multiplexer

from your kernel configuration file and recompile the kernel.

You probably do not need kbdmux if you use just one single type of keyboard.

Kind regards,
