I wonder if this is to do with a faulty BIOS frequency limit. To check this out can you try the following:
Edit /etc/default/grub (you need to do this using root privilege) and change GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash processor.ignore_ppc=1" and then run: sudo update-grub and reboot. Maybe this will work around the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/962947 Title: CPU scaled back to very slow speed, cannot increase speed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/962947/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
