Hi,
When booting into Ubuntu 14.04, and using my new Toshiba L845, the fans do not start working, or do not stoip working, depending on the boot.
Pressing "Esc" when booting, I can read in the boot messages something like:
Not starting fancontrol; run pwmconfig first.
This message also appears in the boot.log.
I tried to execute pwmconfig, but this is my output: 

root@sdf1:/var/log# pwmconfig
# pwmconfig revision 6166 (2013-05-01)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
root@sdf1:/var/log# 

But when running "sensors", I have an output like this one:

root@sdf1:/var/log# sensors

As you can see, I boot'ed my machine just a few minutes ago, and this is
why it's so cool...in some minutes the battery will suffer because of
the fans, or because of the heat.

lsmod qives me this output:

Please, if you have any clue about whan can I do to use my machine with
Ubuntu, I'll appreciate it. Yesterday I was out of my hoouse, and when
back, I noticed my laptop was 90° C...a lot!

Thanks for your time and effort in helping me solve this.
Best regards,

HeCSa.
