I'm having the same problem - first thought it was a specific problem with dual core processors and opened a bug (#213119). After seeing this thread I went back to stock speed and voilla - cpu scaling works...
cpu is dual core E2200 mobo is gigabyte ga-p35-ds3l distro is hardy beta, kernel is 2.6.24-15-generic. had the same prob with gutsy though (kernels 2.6.15-2.6.22). scaling when O/C works well on XP. -- Cpu frequency scaling is limited to stock speeds https://bugs.launchpad.net/bugs/132403 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
