system hang on halt and reboot - amilo pa2510

[Sebastien Chassot]

Hi,

I'm trying to debug basic acpi functionality on my notebook (6.2-stable
amd64). And I don't how to do so.

The problem : 

When I boot with acpi enabled. The system is quite slow, keystrokes take
few secondes to be displayed and mouse pointer is very slow. When I halt
the system the shutdown process hang just before turning off or
rebooting.

With acpi disabled the system run fine but it won't halt neither.


I checked some points from acpi-debug's documentation and added DDB
support and ACPI_DEBUG (please note that I'm not use to debug :)  ) :

	- vmstat -i don't indicate an interrupt storm.

	- I tried use dumped rebuild ASL without any success.

	- acpiconf -s3 don't do anything but -s5 hang too.



I've put some file (boot -v, sysctl,... ) here
http://www.sinux.net/tmp/ACPI_debug/


I just wish to be able to turn on/off my notebook. Thanks for any help.


Regards,

Sebastien


PS: This notebook has an externe power on/off throttle's button it's
quite rare isn't it ? maybe meaningful ?
