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.
Hi Marc,
I just update coreboot from r5692 to r5814 and the problem resolved, before update the code I have met three types of MCE error: Data cache ECC error L2 cache ECC error Northbridge chipkill ECC error
I have not take a detailed look at the code differences yet, but I think maybe it's related to the recent discussion of amd cache broken?
Glad that it is workin now. It is probably not the CAR stuff, that was for fam10.
