[Bug 1203286] Re: [HP Probook 4510s] System fan not working correctly after suspend

 

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.11 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  [HP Probook 4510s] System fan not working correctly after suspend

Status in The Linux Kernel:
  Unknown
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I noticed that since Natty or Oneiric (I don't remember precisely) I have a strange behaviour: after resuming the PC from suspend, the fan starts rotating too fast, even if the PC is not hot. When I first had the problem, I could solve it by (dis)connecting the power cable. In latest versions of Ubuntu, maybe since Precise, this workaround doesn't work anymore.
  I have the mainline kernel downloaded from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc1-saucy/

  I attached some logs, I don't know what else I can provide to help
  troubleshooting this bug.

  I'm using Ubuntu 13.10 amd64.
