It's worth noting that "Processor correctable error"s do _not_
directly cause the machine check panic you reported.

Whatever's causing your correctable errors (maybe bad memory, or
something) may also be causing your machine checks.  Alternately,
depending on whether or not my interpretation of how correctable
errors are/should be handled, the fact that the correctable errors
_aren't_ correctly handled (if my interpretation was wrong) could
eventually cause a machine check.

But "machine check"s are _not_ the same as "correctable error"s...
