First of all, sorry to keep annoying you on this topic, and your help
is greatly appreciated.
As I was experimenting with ACPI, I noticed that on several occasions,
the machine DID poweroff cleanly. After a few kernel compilations and
many poweroffs, I realized that quickly pushing the power button (for
less than 4 secs) did not have any visible effect (no kernel message,
nothing in /var/log/acpid, nothing seen while doing a 'cat
/proc/acpi/event'), _BUT_ it did allow the machine to poweroff cleanly
when doing a 'poweroff -p' afterwards.
In other words, when i press the power button BEFORE doing a 'poweroff
-p', the machine powers down clealy.
When I dont, the same command stops at: "Acpi_enter_sleep_state:
Entering S5". At that moment, the monitor and the machine fans are
still on, but the keyboard wont respond.
The relevant bios settings are:
Power Management:
(x) User define
( ) Disable
( ) Min Saving
( ) Max Saving
Suspend to ram capability:
(x) Enable
( ) Disable
- What would you see as the reason for not seeing any event when
pressing the power button while doing a 'cat /proc/acpi/event'? Is
there a way to monitor acpi events before they enter the
'/proc/acpi/event' file?
- Some docs suggest I should have a '/proc/bus/acpi' directory, which
I dont have. Would that be the problem?
- Could it be a wrongly set bios setting? None explicitely talk about
ACPI though...
- Any ideas? :)
Thank you, once again.
