Try this piece of advice that is given in Arch's very fine wiki here, except that you have to say
options nvidia NVreg_EnableMSI=0 (was placed along nouveau blacklisting file in /etc/modprobe.d/
because you want to disable the new MSI scheme that is now enabled by default in the 325.* driver line (check out the release notes for the new NVIDIA driver for details). That helped in my case (I have a board with a builtin 8200 GPU) and made all those nasty freezes go away for good that started to happen with the new series.
