This is a problem on my first generation MacBook (Core2Duo 1.83GHz). The CPU whines unless the power-saving mode is deactivated. When running Mac OS X, I installed ShhhMBP, which does the trick. Under Ubuntu I can't make it go away, even after changing power-saving modes using CPU Frequency Scaling, or Ubuntu Tweak.
I can't emphasize how serious this is. It sounds trivial but it's a show-stopper for those it affects. It makes using the computer borderline unbearable. I know it's a hardware fault, and that it's a bit galling having to fix somebody else's mistake, but something needs to be done to at least make a tweak possible, even if the user has to intervene. Compiling the kernel is impractical and time-consuming. Ubuntu isn't geared towards hand-made kernels and doing so will break things. -- Unable to set max_cstate on hardy kernel https://bugs.launchpad.net/bugs/206864 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
