I have updated BIOS, unfortunately it changed nothing neither on 3.15rc8 nor on 3.13.0-29-generic.
$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date A14 12/26/2013 I'm not sure if I get you right - do you want me to fill another bug report because of BIOS update? -- 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/1327581 Title: Dell Latitude E5520 Status in “linux” package in Ubuntu: Incomplete Bug description: After the upgrade from 13.10 to 14.04 fan on my Dell Latitude E5520 is working weird. It works in cycles as follows: 100% for about 0.1s 0% 0.1s cca 60% for 2 - x seconds, depending on cpu temperature I think. Before the upgrade fan speed has been set depending on cpu temperature SMOOTHLY with some hysteresis.
