I am running 15.10/beta-2/ on laptop and close laptop everyday (power
suspend / resume only, not shutdown / reboot), and see the problem here
again, once in a while (a few days), the laptop becomes hot, fan start

Title:
[HP ProBook 4530s] Intel Powerclamp is Slowing CPU
Status in linux package in Ubuntu:
Confirmed
Bug description:
I upgraded from KUbuntu 14.04 to 14.10. Immediately, while playing
minecraft with my daughter, I noticed the game was running very
slowly. Even after closing the game, my web browsing slowed to a
crawl.
Looking at the processes in top, I noticed there were 4 tasks called
kidle_inject running at 50% CPU each. After spending a long time
figuring out what caused this, I found out this is caused by the Intel
Powerclamp driver. I never did anything to enable this, and haven't
observed this slowdown before the upgrade.
I found the powerclamp driver in the
/sys/class/thermal/cooling_device5 directory:
root@bkat-HP-ProBook-4530s:/sys/class/thermal/cooling_device5# cat type
intel_powerclamp
root@bkat-HP-ProBook-4530s:/sys/class/thermal/cooling_device5# cat cur_state
-1
root@bkat-HP-ProBook-4530s:/sys/class/thermal/cooling_device5# cat max_state
50
I tried to echo 0 to cur_state, but it still reported -1 when I catted
the value.
There seems to be no obvious way to disable this, and this should not
have been enabled in the first place.
