OK, sorry, but it seems that I was wrong. The old behaviour is back, as soon as I use the laptop on battery. Before it was connected to AC power. That seems to be one piece of the problem. Will try to gather more info, soon.

Then it turns the fan on at 100% speed. And that repeats itself every few minutes, depending on load, of course. BTW, I am running Debian, but this seems to be a Kernel bug anyway. I don't have much time ATM, but will probably file an upstream bug, as soon as I have the time and the necessary info. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1315836 Title: [HP 625 Notebook PC] Fan speed control inactive after suspend to ram and sometimes on reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315836/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
