Well, using a Thinkpad x200 I am observing the same problem (when idle again fan does not reduce its speed).
Unlike in the comments, I was not hit by this issue until now. It worked the last two versions before lucid fine. And under Lucid there was not a problem until the last apt-get upgrade && reboot. Now I am running: $ uname -a Linux lenovo 2.6.32-24-generic $ cat /etc/issue Ubuntu 10.04.1 LTS I remember that in the past I observed this behavior just a very few times after a fresh boot, but it went away after the first suspend/resume cycle (via pm-suspend). -- thinkpad-acpi X200 Thinkpad fan fails to spin down . https://bugs.launchpad.net/bugs/380303 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
