--- Comment #6 from s...@tiscali.it 2012-10-31 19:53:40 --- Because I have no time to compile a vanilla kernel, I tried a Debian precompiled kernel. I used the 3.5.5 linux kernel (taken from here: http://packages.debian.org/experimental/linux-image-3.5-trunk-686-pae, I don't know "how much upstream" is this kernel). The results is interesting anyway: powertop doesn't shows any more the HSDPA Modem consuming power. The device is completely off. So, I think, the bug is related to some patch applied from canonical developers to Ubuntu mainline kernel. Despite this, the overall system power consumption is not improved: the net interface wlan0 (iwlwifi) is now draining a lot of power, about 1.5 W. Enabling powersave mode for wlan0, overall system power consumption drops fron about 9 W to about 7.10 W (a good result). So, I think the problem is related to distributions patch. Correct me if I'm wrong, or if this test is not much reliable. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ Everyone hates slow websites.
