[Bug 1094722] Re: [HP Compaq nx7400] Raring: regression: fan keeps spinning at full speed after suspend

 

Can confirm that this is NOT resolved in Saucy running
3.11.0-15-generic. My computer is a Sony Vaio E Series laptop, model
number SVE14A26CGS. Fan runs fine and responds to temperature changes
upon initial boot but after suspend and then wake the fan goes to 100%
and stays there until I reboot. I've attached a copy of my dmesg log if
that helps.

Bug description:
  With quantal i had no problem to suspend.
  Now with raring the fan spins at full speed after suspend.
  I found this:
  https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.17/+bug/77370/comments/88
  after creating the file the fan stopped spinning at full speed but it never came back
  to the normal speed. It spins still to fast.

  I think there is a bug in the acpi of this laptop. One of the temp sensors is aquatualy the fan speed.
  So i think there is some loop happening. the fan spins because it thinks it's too hot but actualy its the fanspeed itself.

  but however, with quantal (and i think older versions also) this didn't happen.
  So regression.
