Manjaro freezes on entering sleep for the second time

I have a strange problem. Manjaro freezes the second time it goes into sleep. Let me explain…
System starts normal, everything works fine. It goes to sleep after being idle for 30 minutes. It works. I wake it up with keyboard, everything works as it should. Then, when it idles again for 30 minutes and suspends for the second time, it freezes. Keyboard, mouse, monitor turn off but the fans keep spinning and I cant do anything but push the restart button on the PC tower.
This doesn’t happen if AMD Cool ‘n’ Quiet is enabled in BIOS but I would like to keep it disabled.

Can I make it work without enabling AMD Cool ‘n’ Quiet?

I don’t think so.

Really? Too bad… I think that PC is faster and more responsive with that option turned off.
