Tested with archived kernel versions: - 3.0.0-12-generic - 3.2.0-60-generic - 3.13.0-24-generic - 3.13.0-27-generic - 3.13.0-29-generic (default)
Could not regain control of i8k on any of these kernels running Ubuntu 14.04. However, I was able to control the fans with i8kfan in previous versions of Ubuntu — this was an invaluable feature, as my BIOS would clock down the processor instead of turning up the fans when it got too hot. And I am constantly compiling other Launchpad branches, putting considerable strain on my processor. I have a Dell Studio 1558 with an Intel Core i3 @ 2.26 GHz. -- 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/1324372 Title: [Dell XPS 15 (L502X)] i8k kernel module crashes system Status in “linux” package in Ubuntu: Confirmed Bug description: The i8k kernel module (Dell fan control) fails to load in 14.04 (on Dell XPS L502X laptop) -- $ uname -a Linux *** 3.13.0-27-generic #50-Ubuntu SMP Thu May 15 18:06:16 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux $ sudo modprobe -v i8k insmod /lib/modules/3.13.0-27-generic/kernel/drivers/char/i8k.ko modprobe: ERROR: could not insert 'i8k': No such device while "force=1" immediately crashes/freezes the system -- $ sudo modprobe i8k force=1 ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-3.13.0-27-generic 3.13.0-27.50 ProcVersionSignature: Ubuntu 3.13.0-27.50-generic 3.13.11 Uname: Linux 3.13.0-27-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: jerryj 2491 F.... pulseaudio CurrentDesktop: Unity Date: Thu May 29 13:44:32 2014 HibernationDevice: RESUME=UUID=d086eb7b-fb82-4308-a057-9ade21e76147 InstallationDate: Installed on 2014-05-26 (2 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MachineType: Dell Inc.
