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.
