Ok I print low,high which was wrong - it should read 0000000000000004

Oh beautiful. This is wonderful. I've been hoping for a chance to test the MCE
code. Ok you might not agree 8)

Right there is missing \n I'll go fix but the rest of it says

b2 - register valid, uncorrected error, error enabled
0008 - model specific data
0a01 - memory access,
                generic error
                l1 cache
                processor responding to request

So there we are - a real live CPU error
