Christopher, I've tested all the upstream kernels and the bug appears in
all of them. What do I do next? Can I now uninstall upstream kernels?

Title:
  After upgrade to Ubuntu 15.04, wrong temperature readings after wake
  from suspend cause fan to go crazy

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After I upgraded to Ubuntu 15.04, I started having problems with the
  fan going crazy after I wake Ubuntu from suspend. At first, this only
  happened on a few occasions when waking Ubuntu from suspend, but now
  it seems to happen every time I wake it from suspend.

  I'm guessing the fan goes full speed due to the wrong readings of the
  temperature. "sensors" indicates temp4 as 100°C right after I wake
  Ubuntu from suspend, but temp4 is usually only around 30-40°C.

  The problem goes away when I restart Ubuntu. I had no problems of this
  kind on previous versions of Ubuntu.

  I'm not sure if the package responsible is "linux", but I assume it is
  because of this:
