pr_emerg() is rather overkill for a corrected error - on large systems
corrected errors are going to be a routine occurrence (my personal estimation
is "one soft error per gigabyte per month" ... which is pretty much the
same as "one per terabyte per hour" for the people with the really cool

We are also setting TAINT_MACHINE_CHECK for corrected errors - perhaps
this made sense when systems were small and machine checks were rare and
scary. But I think we need to start working with the reality that
corrected errors are normal events.
