I am usually up to compiling lp:inkscape , and when my fan speed decreases while compiling, that is a problem. A big problem, in fact. Now, on 14.04 with kernel 3.13.0-29-generic, I can no longer use anything from the package belonging to the branch lp:i8kutils, instead receiving this error message: ~# i8kfan 2 2 can't open /proc/i8k: No such file or directory Manually inserting the module also returns an error, to make it seem such as that the kernel was not compiled with i8k support. ~# modprobe i8k modprobe: ERROR: could not insert 'i8k': No such device ~# insmod /lib/modules/3.13.0-29-generic/kernel/drivers/char/i8k.ko insmod: ERROR: could not insert module /lib/modules/3.13.0-29-generic/kernel/drivers/char/i8k.ko: No such device I also tested this with archived kernel versions on the same device: - 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) I could not regain control of i8k on any of these kernels running Ubuntu 14.04. Related bug #1324372 "[Dell XPS 15 (L502X)] i8k kernel module crashes system" Upstream kernel (3.15.0-031500rc7-generic) does not truly fix the issue either: while I can control the fan, it appears as though the kernel is not effectively blocking the SMM BIOS control mechanisms from regaining control in about 5 seconds. To put it more simply: running i8kfan to control the fans works — for 5 seconds. Then the fans turn off completely again. Not good for a machine that is at a severe overheating risk. There is no way to keep the fans on, even during intensive CPU usage. Reaching its maximum operating temperature, the machine shuts down to avoid serious damage to the processor.
