From the freedesktop.org bug:
It seems to me that this is in fact a CPU related problem. Since July 25 I don’t have any problems. My system is pretty stable. What helped was to add idle=nomwait to my GRUB command line. This has fixed those problems for me.
Please try to add idle=nomwait to your GRUB command line. I think this bug can be closed.
