I had this same problem, search the lkml if you're interested in investigating this further, I had the problem, was told it was hardware, replaced my motherboard with the same model, the MCE continued to occur, replaced the motherboard with a different model and the MCE went away. It was some Biostar IIRC, but you can check the archives if you really want to find out. Good luck -- avuton -- Anyone who quotes me in their sig is an idiot. -- Rusty Russell.
