Do you have  _GTS? Can I ask you to try to comment out call to it (with
_PTS not commented out)?

No :( Actually it may not work here, because you are very near to
switching off many devices and console may not be available at this
point.

Thanks,

Could you post your whole DSDT and dmesg?
BTW, if you enable debug in ACPI and do "Store ("BLA-BLA-BLA", Debug)"
in any method of DSDT, ACPI will print it to console (even from _PTS and
_GTS).

Thanks,
	Alex.

Hi Andre,

Have you tried to disable the call to _SST? It is at the end of same
function acpi_enter_sleep_state_prep(). Can it be that kernel hangs
_after_ the call to _PTS? 

PTS stands for "Prepare-to-Sleep", so it can disable some hardware
(com-port or video). May be this is the reason, why you cannot get any
debug prints.

Regards,
	Alex.

Hey guys!

I've done some more debugging to figure out why my notebook won't shut down 
anymore. To recap, it works up to 2.8.6.1-mm3, but no kernel thereafter.

The following call in /drivers/acpi/hardware/hwsleep.c hangs:
 status = acpi_evaluate_object (NULL, METHOD_NAME__PTS, &arg_list, NULL);

This is in acpi_enter_sleep_state_prep(). 
When I comment out that line, it continues on just fine and shuts off.

I'm very surprised by this, since a diff -ru between mm3 and mm4 brings up no 
changes in drivers/acpi at all. So I don't know why it works in mm3 and not 
mm4 (and above).

Also, I've put Debug statements in my DSDT in the _PTS function, but somehow 
they are not printed to the console (or dmesg), even so I have 
CONFIG_ACPI_DEBUG=y
CONFIG_PM_DEBUG=y
in my kernel config.
Somehow I had managed to get the DSDT debug strings onto the console once 
before, but I forgot how to do it. Any tips would be appreciated.

Belo is my DSDT code, method _PTS for reference.

I've downloaded the ACPI specs and will try to read up on what PTS is supposed 
to do. Maybe I'll come up with something.

Meanwhile, if you guys have any ideas, please let me know!

Thanks so much for your help!

Regards,
   Andre
