Title:
  Acpi problem??? and fan do not work properly

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Laptop DV6 6030EL

  I have installed recently the new kernel 3.11 on ubuntu 13.04 to solve
  some problem with the radeon card and improve the support of i915.
  From the beginning I have noticed something strange, some sensors from
  psensor did not show up as for instance the lmsensor radeon pci or the
  coretemp, the backlight was again set to the maximum value while
  usually what I do is:

  sudo gedit /etc/default/grub
  GRUB_CMDLINE_LINUX="acpi_backlight=vendor"
  sudo gedit /etc/rc.local
  echo 3000 > /sys/class/backlight/intel_backlight/brightness 

  The radeon sensor in kernel 3.10.10 was showing -128 since I have
  turned off it by doing

  sudo gedit /etc/rc.local
  modprobe radeon
  sleep 1
  echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
  exit 0

  With the new kernel at the startup the temperature was much higher
  than usual and backlight was not set to the right value. The biggest
  issue with the new kernel is the fan stops to work or in some case
  seems to lose power (like start and stop). I have switched back to
  3.10.10 but this bug could be very critical. I did not noticed the
  problem immediately and the laptop was almost burning.

  Has someone noticed similar problem on the new kernel?

  Thanks
