8 seconds power button timeout no longer working (regression)

Usually, after a couple of seconds holding the powerbutton, init was signalized
a reboot. if that doesn't react, the system was shut down. This no longer works.
When I keep pressing the power button, I see the kernel incrementing the seconds
counter, but the system just doesn't shut down nor does it turn off.

This bug is still present on my GTA01Bv4 with the following packages (built with

kernel-image- -
sysvinit - 2.86-r36

When X is shut down (or crashes) and the power button is held down, messages are
printed to the screen but the device does not shut down or power off.

  • Owner changed from michael@… to openmoko-kernel@…

Problem still present in 2.6.24 -- neither the the controlled shut down
(signalling init to shutdown) nor the forced shut down works as expected.

Reassigning to default owner.

I'll take a look at this.

Well on GTA02 we do track the 3 seconds and we do appear to issue a signal
(SIGINT) to init. I tried it first having booted with init=/bin/sh and
naturally ash didn't react to SIGINT.

However if you come up in the GUI on GTA02 and hold the button 3 seconds, it
brings up the power menu in response to the SIGINT to init.

SIGINT does not mean "shutdown" (SIGPWR) but "interrupt". So it seems this is
intentional and works on GTA02 as far as that goes.

Now if it is desired that if you keep that button down 8 seconds it tries to
shutdown, that can be added. Is that what we want?

No, neod brings this power menu up when you hold the button for one second. It
looks like SIGINT is not getting sent.

The behaviour we want (and which we had a couple of kernels ago) is:

1.) Four seconds power hold => SIGINT to init
2.) Eight seconds power hold => forced shut down

  • Status changed from new to closed
  • Resolution set to fixed

Matt has done some work on this which is in the buildhost kernel now. Please
try >=4131 kernel from there and reopen this bug if it doesn't make you
happy :-)
