Subject: [2.6.12-rc1][ACPI][suspend] /proc/acpi/sleep vs /sys/power/state issue - 'standby' on a laptop
Date: Mon, 28 Mar 2005 02:49:04 -0500 [thread overview]
Message-ID: <200503280249.05933.shawn.starr@rogers.com> (raw)
Hello,
I've noticed something strange with issuing 'standby' to the system:
when echoing "standby" to /sys/power/state, nothing happens, not even a log or
system activity to attempt standby mode.
However, trying echo "1" to /proc/acpi/sleep the system attempts to (standby)
and aborts:
[4295945.236000] PM: Preparing system for suspend
[4295946.270000] Stopping tasks:
=============================================================================|
[4295946.370000] Restarting tasks... done
We get no reason as to why it quickly aborts.
[4294672.065000] ACPI: CPU0 (power states: C1[C1] C2[C2] C3[C3])
[4294676.827000] ACPI: (supports S0 S3 S4 S5)
What is '1' in /proc/acpi/sleep? standby mode is not the same as suspend to
ram? when I put a normal desktop in standby mode its still 'on' but the hard
disk is put to sleep and the system runs in a lower power mode.
Shawn.
