Careful users should wait a few days to get the fixed kernel as a normal

Christopher: Can the fix (Revert ACPI / AC: convert ACPI ac driver to
platform bus) be backported to the trusty 3.13 kernel? Looking at the
upstream bug (https://bugzilla.kernel.org/show_bug.cgi?id=71711), it
affects quite many laptops and their fan control is now also broken with
the stock Ubuntu
It was way too easy: The bad commit was reverted:

Jörg-Karl Bösner, the next step is to fully reverse commit bisect in
order to identify the fix commit. Could you please do this following

?

Jörg-Karl Bösner, could you please test the latest mainline kernel via

advise to the results?

OK, bisect will be finished next week (at least, I hope it so). ATM it

Hello fellas,
I have a similar problem after fresh new instal of 14.04 Lubuntu on HP
nc6120. Chose Lubuntu as it is lighter than Ubuntu for this machine. The
fan behaves as described by Jörg. Similarly psensor does not show fan at
all, while the temperatures it shows are frozen at boot level

I experienced similar problems with my laptop HP Compaq nc6120 in Ubuntu
14.04. The bug is also present in Debian testing when using kernel 3.13
but not with kernel 3.11. Therefore this seems to be a wider laptop
issue and not only Asus-specific and also probably caused by bug in the
upstream
Hello Joseph!
I did try it with the new upstream kernel, it did NOT solve the problem.
The problem also occurs on all kernels when suspending to RAM and
starting it again. The fan behaviour is the same as when the machine is
booting regularly: The speed is frozen to the actual hardware
Jörg-Karl Bösner, the next step is to fully commit bisect from Saucy to

Fan speed is also frozen on HP 6830s an xubuntu 14.04. I downgraded to
