Shutdown/poweroff/halt waits for key press

[Chris Van Steenlandt]

Hey,


I just installed FreeBSD 11.2 on old Toshiba laptop 
(http://www.toshiba.be/nl/discontinued-products/satellite-c650d-11j/) 
for which I had to do a BIOS update.

During bsdinstall I noticed something very peculiar : in the beginning 
of the install the program searches for keymap files. However the 
message 'fetching keymap files' appears in the interface and hangs (I 
noticed a cursor in the bottom left of the screen). Until I press a key 
on my keyboard and then I get the list of the keymap files. During 
several (but not all) points where in bsdinstall I had to move from 
screen to screen, I could only do so by pressing a key (I used <shift> 
and not <enter> because this key is used within bsdinstall) .

Once installed, the boot messages appear fluently without hangs. However 
when I am logged in as root and I type 'poweroff' again a few lines 
appear and then it hangs ... until I press a key. I have to press quite 
a few keys for the shutdown process to advance until it is completely 
shut down....


Apparently, somebody experienced the same problem under Debian 
(https://superuser.com/questions/364319/computer-freezes-at-random-times-until-key-is-pressed) 
....
So I looked if I could turn off ACPI but then my laptop won't boot.
I also tried to disable the subsystem 'timer' in ACPI (based on the 
answer of the Debian post) by adapting /boot/loader.conf 
(debug.acpi.disabled="timer") but the problem remains.

A verbose boot does not reveal any ACPI specific errors.

Thanks in advance for any suggestions,


Regards,


Chris
