Same problem here (Ubuntu 14.10, AMD64). Here it seems to be related with Intel P-state: http://www.webupd8.org/2014/04/10-things-to-do-after-installing-ubuntu.html (1.5 section)
Here a benchmark about using or disabling Intel P-state: http://www.phoronix.com/scan.php?page=article&item=intel_pstate_linux315&num=1
To solve this bug: gksu gedit /etc/default/grub than change GRUB_CMDLINE_LINUX_DEFAULT="quiet ... ..." to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=enable"
Obvoiusly this will disable Intel P-state
