[Bug 1224141] Re: Acpi problem??? and fan do not work properly
Does the fan start to work without stopping if you boot into a prior
kernel, such as 3.10? We should rule out any hardware issues with the
fan. If the fan does work normally in 3.10, we can perform a bisect to
identify what commit introduced this as a regression.

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
