[Bug 881593] Re: Hardware temperature hazardously hot

 

The currently under-development Ubuntu 14.04 "Trusty Tahr" is based on
the 3.13 kernel which enables DPM by default (without needing the
radeon.dpm=1 boot parameter I mentioned above) for Radeon HD 4000
through Radeon HD 7000 series graphics processors but with some specific
ASICs being excluded. You can download a pre-release version at
http://cdimage.ubuntu.com/daily-live/current/ and the final release is
scheduled for April 17th, 2014 as per
https://wiki.ubuntu.com/TrustyTahr/ReleaseSchedule

Title:
  Hardware temperature hazardously hot

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  Parts of the notebook computer become painfully hot to the touch while
  running Ubuntu, and the fan is not running.  When I boot back to OS X,
  the fan kicks in and runs until the computer returns to being cool to
  the touch.  What metrics do I need to collect to help fix the problem?

  There seem to be two problems, one is that the hardware near the
  screen (GPU?) getting WAY too hot, another is that the fan is not
  turning on when the hardware gets too hot.

  This is the recent ubuntu:
  $ lsb_release -rd
  Description: Ubuntu 11.10
  Release: 11.10

  This affects the lifespan of the computer and it could conceivably be used to burn out and destroy the hardware very early.
