Tested under 3.0.0-13-generic #22-Ubuntu SMP. Has identical fan behavior, max fan speed is never triggered while kernel is loaded. Instead machine is severely under-clocked.
** Tags removed: needs-upstream-testing ** Description changed: I am running Ubuntu 11.10 on a laptop and the heat management is very bad. The system will heat up and under clock to avoid damage. When the system is restarted and in GRUB the fan speed will go to MAX. The moment the kernel loads the fan speed drops dramatically. Why not increase the fan speed to the max to try and avoid under-clocking? In fact i have never seen my fan speed max out on Ubuntu! Awful! - Clearly this is incorrect behavior that is not only damaging but severely limits the power of the machine. I will be Channing operating systems until this issue is addressed. - --- + Clearly this is incorrect behavior that is not only damaging but severely limits the power of the machine. + --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
