[Bug 1535426] Re: CPU runs at high speed after upgrade
Note, it's not continuously at max speed, it's varying between 2.9GHz
and 3.2GHz. But it never slows down. My load average is very low.

Title:
CPU runs at high speed after upgrade
Status in linux package in Ubuntu:
New
Bug description:
After a dist-upgrade from 15.04 to 15.10, moving from kernel 3.19.0-43
to 4.2.0-23, my laptop CPU runs continuously at 3GHz, and never slows
down to 800MHz, as it used to. This has reduced my battery life from
24 hours to 8 hours.
