My laptop (Compaq 6720s, bought in 2008) behaves also like this. After "waking up" the fan is turning on full speed with raring. With quantal it behaves as it should. I tried all kinds of things to cure it (GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=linux" etc). Nothing worked. But the file /etc/pm/sleep.d/99fancontrol.sh as mentioned by filip (bandit-s-fw) on 2013-02-09 above works 100%. Thank you very much. Every time there is a new linux kernel in the updates, I make the file /etc/pm/sleep.d/99fancontrol.sh non-executabele. Then I bring the laptop in ram-sleep and wake it up again to test if the problem still is there. Until now I need to make /etc/pm/sleep.d/99fancontrol.sh executable again very quickly because the fan is going wildly.
Ofcource it would be even better when this tweak wasn't needed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1094722 Title: Raring: regression: fan keeps spinning at full speed after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1094722/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
