Created attachment 829525 [details] lspci output / dmidecode output / /proc/cpuinfo Description of problem: Right from the beginning, after I installed Fedora 19 x86_64 (Kubuntu) from scratch, the fan of my laptop went crazy. During some point of the startup process (somewhere after the blue Fedora logo appears in the middle of the screen, if that helps) the fan just goes up to maximum speed AND STAYS THERE. I tested it and even after a complete day it stays at maximum speed (really annoying also for the people around you). This has nothing to do with components overheating, since KSensors tells me that CPUs and board are comfortably within the middle of the green area. Additional Information: This did not happen with a 32bit Fedora 17 (Kubuntu) I was running before on the identical hardware. Version-Release number of selected component (if applicable): 3.11.8-200 but it also existed with older kernels in Fedora 19 How reproducible: Always, no exception. Steps to Reproduce: 1. Just do a complete boot up (this means no recovery from "suspend to RAM" or "suspend to disk") of the machine. Actual results: Fan runs at maximum speed and does not slow down. Expected results: Speed up at the end of the boot process, then slow down again. Additional info: The workaround that I found goes like this: 1. Boot up the machine --> fan at maximum 2. Put it back to sleep with "Suspend to RAM" 3. Hit powerON again --> fan at low Maybe that helps to track the down the settings that make the fan go crazy.
Hi Thomas, does it happen if you boot with 'acpi=off'. Can you also attach dmesg output and lsmod output to this bz. thanks, Michele
Hi Michelle, thanks for the quick reply. Yes it also happens if I boot with "acpi=off". I have attached the outputs from dmesg and lsmod as requested. If you need anything else, just let me know. Bye, Thomas
