After upgrade to 15.04, wrong temperature readings cause fan to go crazy

Question

Since I upgraded to 15.04, twice after I had started it from suspended state Ubuntu would right away start spinning the laptop fan like crazy since it thought that one of the temperatures was 100°C (as the sensors command indicated). The particular temperature is usually around 30-40°C.

This happened only when I woke Ubuntu up from suspended state, and only twice so far, even though I've woken it up numerous times since the upgrade.

The problem doesn't go away until I restart Ubuntu.

Thoughts?

EDIT: Now this seems to happen whenever Ubuntu wakes from suspension.

sounds like a bug - probably better to report it to launchpad http://askubuntu.com/questions/5121/how-do-i-report-a-bug — fossfreedom, Apr 25 '15 at 10:43

I have HP 6910p and facing similar problem. It was temporarily solved with booting from old 3.16.0-34-generic kernel (via Grub Customizer).
