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. bug closed. please feel free to re-open it if you can reproduce the problem again in a vanilla kernel. -- 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. -- Minimize network downtime and maximize team effectiveness.

https://bugzilla.kernel.org/show_bug.cgi?id=42690 --- 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.

[Bug 42690] powertop reports power regression on Globetrotter HSDPA modem
https://bugzilla.kernel.org/show_bug.cgi?id=42690 --- Comment #3 from s...@tiscali.it 2012-07-28 00:30:14 --- I'm investigating the issue. Changing the /sys/bus/usb/devices/usb4/4-1/power/control from on to auto, have the right effect to auto-suspend the HDSPA modem. This will save about 500 mW. More investigations revealed that in Ubuntu 12.04, this device has the maximum power usage setted to 500mW (found with the command lsusb -v, at the line MaxPower). So suspending this device has less effect on power consumption compared to previous version of Ubuntu (~ 1W). This mean that there is something else that had raised its power usage. (this can be related only to Ubuntu and not Linux) However, the changes at the file /sys/bus/usb/devices/usb4/4-1/power/control will reset at the next reboot of the netbook. 1) So, how can I make that changes be permanent? 2) If these are not permanent, this means that some other process at the boot will automatically check the devices and will sets the power properties to them. Can someone tell me which process do this control (because is obviously bugged)? If someone can help me with these questions, I can continue to investigate this issue. Thanks. (P.S. Kernel 3.5 also have this issue) -- 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. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
