I haven't worked with K8 is a while, but it seems like this could be a real CPU problem. Do you have another CPU to test with? The other possibility is that there is a missing errata or workaround for your CPU. You could review the AMD K8 revision guide for cache and MCA/MCE issues. Please let us know what you find.
