I'm having a different variant of the fan problem since I upgraded to 2.6.27-10. When the computer boots, the BIOS sets the fan running at medium intensity, and under normal conditions the Linux kernel stops when it begins probing devices (when the splash screen appears). Now it doesn't, and the fan simply keeps running.
Under normal conditions, the four fan intensity levels are triggered at 61, 71, 81 and 91 degrees when temperature increases, and the speed level is reduced at 50, 60, 70 and 80 degrees when the temperature decreases (i.e., reaching 50 means stopping the fan). When the fan starts non-stop from boot, if I heat up the CPU to 61 degrees (first trigger), the fan switches to the lowest intensity, and then it stops if I allow it to cool down to 50 degrees. I use a bash script to warm up the CPU, which I've attached in case anyone wants to use it. I usually need to block the air vent with my hand to prevent the running fan from spoiling the trick. Keep an eye on the temperature if you use this! But I've also had cases where the fan won't respond to increasing the temperature. This is getting annoying.. does anyone have any idea of what may be going wrong here, or where to look to gather clues? ** Attachment added: "warmup.gz" http://launchpadlibrarian.net/20406179/warmup.gz -- fan never turns off https://bugs.launchpad.net/bugs/226397 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
