Title:
  ubuntu 15.04 overheats

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  On 2015-04-26 I upgraded to Ubuntu 15.04 (from 14.10). Since then, my
  notebook (HP envy dv6) fan is nearly always on, and the notebook
  switched off several times, probably due to overheating. Each time I
  was working with Firefox; watching the "livestream" of
  www.tagesschau.de seems to be a good way of reproducing the problem.

  Going back to the 3.16.0-31 kernel (still offered by grub) seems to
  circumvent the problem. When I boot 3.16 the fan runs only
  occasionally. My first 15.04 kernel was 3.19.0-15, today I got -16 but
  the problem is the same.

  Before the machine switches off (it does not shut down Linux but just
  goes out) "top" shows me eight instances of "kidle_inject", obviously
  desperately but hopelessly trying to keep processor load down. Under
  the 3.19 kernel the "plugin-container" process goes to loads of more
  than 100 % (on a four-core box), under 3.16 it never goes beyond 60 %.
  Note that between the "overheat" and the "normal" scenario I change
  only the kernel in the boot menu, all other binaries are the same
  (15.04). Especially, it's the same firefox.

  I fear that within a couple of weeks more kernel versions will arrive
  at my system and eventually push the working 3.16 kernel out of my
  grub menu, and then I shall have no way left of running my system for
  more than 20 or 30 minutes.
