Hi Wolfgang,
I've been trying to find what's the problem whole day and I think
I found the solution/workaround.
You are pretty close, but
/usr/lib/pm-utils/power.d/wireless does nothing in my case,
I only get the message in pm-powersave.log:
--------------------------------------------------------------------
Running hook /usr/lib/pm-utils/power.d/wireless true:
Turning powersave for wlan0 on...Error for wireless request "Set Power
Management" (8B2C) :
SET failed on device wlan0 ; Operation not supported.
Failed.
/usr/lib/pm-utils/power.d/wireless true: success.
--------------------------------------------------------------------
But I found the script causing problem is:
/usr/lib/pm-utils/power.d/pcie_aspm
Very simple workaround is to create empty file "pcie_aspm" in
/etc/pm/power.d folder with execute bit disabled. What this does it
prevents /usr/lib/pm-utils/power.d/pcie_aspm from running.
It's better way than to delete /usr/lib/pm-utils/power.d/pcie_aspm,
because that can be recreated in future updates.
I wish you people give a try and check whether this help.
