[mythtv-users] Annoying shutdown problem

I've been running MythTV 0.27 or Debian Jessie for a while without 
problem. I've just switched to 0.28 on Debian Stretch and have been hit 
with an annoying problem on the frontend.

The frontend is netbooted and controlled by a Harmony remote sending 
commands to an iMon receiver.

I map the power command on the remote to a shutdown command in the 
lircrc config file. On Jessie this worked fine. The power button was 
mapped to "sudo halt" and the system shut down as expected.

On Stretch/0.28 no such luck. The system shuts down OK but never powers 
off. It gets to a point where the last message is (something like - 
don't remember the message) "Shutdown complete, system halted" then 
freezes, i.e. the fronted does not power off and is not responsive to 
anything but manually pressing the physical power button on the frontend 
itself. It then boots on the next powerup as expected.

I've tried changing the shutdown command, all of:

/sbin/halt
/sbin/shutdown -h now
/sbin/poweroff

behave the same way, i.e. the system does not power off.

 From googling I've tried adding acpi=forced as a kernel parameter but 
this has no affect.

Interestingly if I ssh into the frontend or attach a keyboard and login 
to a different terminal and execute any of the shutdown commands the 
frontend powers off correctly.

To me, this suggestes that there's some interaction between lirc and the 
shutdown process.

Any suggestions - it's extremely frustrating at present having to 
manually poweroff the fronted!

Cheers,
David
