Hi, I bought a new Laptop, HP ProBook 4510s, and of course installed Arch Linux on it. Now everything else is just perfect, but I'm having problems with suspend. Computer suspends, and wakes from it, but after waking from suspend fan runs at maximum speed, and never slows down. My guess is that this has something to do with some module controlling the fan, but I can't figure out what module and what should I do to fix this problem.
Log file /var/log/pm-suspend.log is like this:

Maybe your fan goes to the top because the CPU is running 100%, my AMD64 goes to 100%(and the fan) if its module (powernow-k8) is not loaded.
Try returning from suspend, and running "sudo cpufreq-set -g ondemand". If this works, just script this command after suspend.
Otherwise, try laptop-mode-tools. Those might help. You don't mention your DE, if it's KDE, you need acpi installed to suspend (it hangs on me without it after suspend).

Thank you for you answer, my problem is not CPU usage, it's in some 2-10% all the time. I'll try laptop-mode-tools. I'm mainly using KDE, but the problem is the same in LXDE too.

What's your "sensors" output? (Package lm-sensors, I think) My cpu could run as yours, yet rise above 50 C all the time when I had that problem.
cpufreq-utils is also VERY handy.
The thing is that your CPU may be using 2-10 percent, BUT within the performance governor (same as NO governor at all), it's kinda the same
as, i.e, 20 percent with the "ondemand" governor, but "cooler".
This may mean (I think) that your CPU is receiving max power all the time after suspend, but doesn't need ALL that capacity to work (hence the 2-10 percent). That can explain the low CPU usage AND a high cpu temp (if any).

Hi,
I had the same problem with my HP6530b. I use pm-utils for suspend and hybernation, which is, as far as I know, also used by KDEs Powerdevil.
The solution was to add a file named "config" to /etc/pm/config.d/ with:
SUSPEND_MODULES="fan thermal iwlagn hp_wmi wmi" # the list of modules to be unloaded before suspendThis solved my problems with the fan running at 100% and the sometimes broken Wifi/rfkill-Switch after returning from suspend.
