I'm currently on Kernel 3.10.11 all the sensors are detected well. The fan is working fine I cannot almost hear it because the temperature is 44°. I never had this low temperature on linux and I'm very happy about the kernel 3.10.
I was moving to 3.11 because of the patches introduced for the amd card. As I mentioned before I noticed something strange from the beginning in 3.11. Could be related to the radeon card that have not been turned off properly. The backlight command didn't work and I'm suspecting also vgaswitcheroo had some problem. Yesterday before the compleate shut down of the fan I had the impression that it was doing "start and stop" sequentially but it could be that the temperature for some reason was raising quickly. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1224141 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?
