This is adapter (driver) specific, but you might need to unload the
adapter's driver module to cause the WOL setting to be implemented. I
see similar issues with my Intel D201GLY2 board (uses sis900 driver for
the network adapter) that runs CentOS 5 and fixed the issue with the
following /etc/pm/config.d/modules file:
Code:
--------------------
# Must remove network module or system will not Wake on LAN from ACPI S3/S4.
# Suspect that WOL setting is applied when driver module is unloaded as part
of normal
# shutdown process, so unloading module has same effect
#
# Have pre-pended "mii" module as it depends on "sis900" and must be unloaded
before
# the latter. Determine order of dependencies using lsmod to see dependencies
# for the driver
SUSPEND_MODULES="mii sis900"
RESUME_MODULES="sis900"
--------------------
This caused the system to WOL from ACPI S4 (and presumably would also
work in S3, except it's a Celeron CPU that doesn't support S3).
