Subject: 2.6.31 regression: iwlagn power_level no longer works
Date: Tue, 01 Sep 2009 17:26:00 -0400 [thread overview]
Message-ID: <4A9D9168.2070608@mit.edu> (raw)
On 2.6.30.5, I can echo 1 >/sys/class/net/wlan0/device/power_level, and
the value changes to 1, my wakeup rate goes way down, and my power
consumption (as measured by powertop) drops noticeably.
On 2.6.31-rc7, I can still echo 1 to that file, but nothing happens, and
the value I get if I 'cat power_level' remains at 0.
My kernel configs are as identical as 'make oldconfig' knows how to make
them.
Any ideas?
