Another check which someone suggested to me a while ago but I've been too lazy to setup is to ssh into your MBP remotely and remove as many modules as possible, including usb. I read reports on the kernel mailing list that some machines don't go into C4 if the usb module is loaded but unfortunately on the MBPs this is needed for the keyboard so to test this you have to log in remotely.
Also, there's a post on phoronix.com http://www.phoronix.com/scan.php?page=article&item=683&num=2 where the author claims he's checked and the ATI radeon x1650 pro (not exaclty our model) runs much hotter on Linux than on windows (and presumably os x) so a large part of the problem might be the ATI drivers. I'm not sure if powerplay works on this card but the problem may be that the driver is so ineffecient that even using powerplay won't buy us too much energy saving. Do macbooks take as bad a bit on battery life as MBPs? I've heard three hours from some MB owners on the list which seems to still be pretty bad compared to what they should be able to get but it would be interesting to get more concrete data on this. cheers, Sheer On 4/18/07, Nicolas Boichat <[EMAIL PROTECTED]> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Hi, > > (switched to mactel-devel list, more appropriate I think) > > Sven Anders wrote: > > Hello! > > > > Some data of my machine (for reference): > > > > # dmidecode | egrep '(Version|Release)' > > Version: MBP22.88Z.00A5.B01.0611031551 > > Release Date: 11/03/06 > > Version: 1.0 > > Version: PVT > > Version: Mac-F42187C8 > > Version: Intel(R) Core(TM)2 CPU > > Version: Intel(R) Core(TM)2 CPU > > > > > > This is what I found out: > > ------------------------- > > Wow, impressive report, that's really unfortunate and frustrating it > doesn't really helps us to improve power management on Linux... > > > The following hopes I have: > > > > 1) The auto USB suspend framework will solve the too-many interrupts > > problems. > > Have you tried this kernel option? > CONFIG_USB_SUSPEND: USB selective suspend/resume and wakeup (EXPERIMENTAL) > > Looks interesting...
