ACPI Power Button Event problems(?)

ACPI Power Button Event problems(?)

[Wes Janzen]

I'm having an interesting, and relatively benign problem with ACPI 
events.  I downloaded the ACPI daemon from SourceForge and with 
2.6.0-test1-mm2 when I pressed the power button, ACPI would be deluded 
with PWRF events until I pushed the button again or acpid was 
restarted.  That's easy enough to work around, but with 2.6.0-test2-mm1 
the events never stop.  Restarting the daemon makes no difference, nor 
does pushing the button have any effect.  That wouldn't be too big of a 
problem if I was using the power button to restart the PC, but I'm using 
the event to kill sawfish since it likes locking up (and disregarding 
any keyboard input) leaving me with no recourse but to press the reset 
button otherwise.  So, it works great for the first lockup, but I can't 
reset the power button event so I'm stuck with the reset button on the 
second round.  Unless I want to reboot, which I'd rather not. 

Is this a bug in 2.6.0-test2-mm1 or was the bug the fact it could be 
cancelled in 2.6.0-test1-mm2?

Thanks,

-Wes-

I am guessing that it is not a bug in acpid since stop it didn't help.
You could try a
cat /proc/acpi/event
to make sure that you are actually getting these events no stop.
I am guessing that it is a faulty dsdt since you got the same the
behavior on the different kernel.
Can you tell if this also happens with 2.4 kernel?

I did the cat /proc/acpi/event shortly after implementing my script and 
finding out it was continually being called after pressing the power 
button.  I got/(still get):
button/power PWRF 00000080 00000001
...
button/power PWRF 00000080 00006bbb
... etc.

Of course, with 2.6.0-test1-mm2, it would stop when I restarted acpid or 
pushed the power button again.  With 2.6.0-test2-mm1 that has changed in 
that stopping the events requires a reboot.

I can recompile my 2.4.18 with ACPI support and see what happens if that 
is necessary...just let me know.

Thanks.
