  I mostly see this type of error due to correctable memory errors.  The 
machine check frame apparently is different for the various models of 
alphas, and doesn't appear to be documented for many of them, so the 
contents which presumably indicate the memory address isn't easily 
available.  I've thought about adding some kind of verbose option just to 
dump some random information in the machine check frame, but haven't 
gotten motivated enough to even look at it.
