I had a similar problem. It seems to be caused by multiple cores accessing the cf8/cfc interface simutaneously. Using the MMCONF_SUPPORT completely eliminates the problem for me.
All AMD CPUs should be using MMCONF_SUPPORT now. I thought that had been added several months ago.
Xavi brings up a good point, Check the BKDG and revision guide for settings and bug fixes that need to be implemented for newer CPUs. Also check the the FID/VID setting is correct for the CPU.
