I have the "no or unknown cpufreq driver is active on this CPU" both before and after suspend. It is no big deal anyway: rather than waste hours on this, I guess I'd rather not suspend anymore.

Thanks,

Rémi

What driver is loaded before suspend?

My guess: your distro does not reload the corresponing kernel module after suspend...

On Ubuntu the driver does not seem to be loaded as module, therefore I can not check...

if you know what module, check lsmod to see if it is loaded

after suspend I would modprobe the module and hope it works?!

Thanks Nick,

It was fun to participate again.

After the tournament, I noticed that my CPU was about 3x slower than usual. It turns out it is because of a bug in my Linux distro (Mint 17). After suspend, the CPU becomes slow.

I have not yet found a proper way to fix this. Maybe someone on this list can help?

cpufreq-info returns this:
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpuf...@vger.kernel.org, please.
analyzing CPU 0:
  no or unknown cpufreq driver is active on this CPU
  maximum transition latency: 4294.55 ms.

So none of the cpufreq-related workarounds I found on the web works.

This is a bug report of the same problem:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1102318
But I can't get indicator-cpufreq to work, maybe for similar reasons: whenever I drag the icon to the panel, nothing happens.

This also suggests indicator-cpufreq:

I'd be grateful for any help.

Thanks,

Rémi
