The ODD versions of Linux distributions are stable.
The ODD versions of the Linux kernel
are considered development versions and should not be used by the public.
The freezes could be related to a configuration problem or a hardware problem.
Try pressing ALT + CTRL + BACKSPACE ( not DELETE! ) does that kill the GUI? If it does then just the GUI froze. If it does not you may have bad or unstable hardware.
If you have a LAN where you are and your computer is on the network see if you can still ping it or ssh to it when the GUI freezes to see if it's just the GUI that froze or the whole computer. If it is the whole computer you need to individually test your hardware.
