Title:
  lm-sensors does not detect fan sensors, provided by i2c_i801

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  lm-sensors cannot detect my fan sensors, so my fan is not working at
  all and that makes my laptop have very high temperatures, which is
  very bad for it. I have tried several times to run sensors-detect, but
  only coretemp is detected, although for Ivy Bridge (Panther Point
  chipset), there should be more sensors provided by i2c_i801.

  While looking for a solution, I have found an ongoing discussion on
  http://forums.gentoo.org/viewtopic-t-946718-start-0.html, where they
  have concluded that this is probably a kernel bug.

  I have created a bug report couple of days ago for lm-sensors, but
  they have it was marked as invalid. I create another one, since it is
  definitely a bug, a very problematic one, since my laptop has crashed
  already couple of times due to overheating.
