I have the same problem after my upgrade to natty, cpu firmly stuck at 1.5Ghz. installed cpufrequtils and can change governor now but it's no help, powersave sticks to 187Mhz everything else sticks to 1.5Ghz. had to modprobe p4_clockmod to get any governor working.
Heat of may fanless mediapc has doubled since the upgrade. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/797190 Title: Ubuntu 11.04 Natty upgrade underclocks and disables CPU scaling To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/797190/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
