MCA = Machine Check Architecture.
DRD here probably refers to a data read cycle.
SNOOP has to do with hardware-maintained cache coherency.
DCACHE = data cache.
Google and/or Wikipedia may help with the details.

I _think_ the COR refers to a corrected error, but that could be
either transient (a random bit-flip, possibly due to a cosmic
ray hit) or permanent (a bit in the cache has gone bad). In the
latter case I'd expect ongoing error messages, rather than just
two isolated occurrences.

I would say not, unless the errors become frequent or uncorrectable.
