Word on the street now is that it may have been something called "core
lockup" on both engines. Bombardier claims it's never happened on an
in-service engine, however.

If I read that right (and I'm not sure I did), "core lockup" is something
that happens to an engine that has been stopped. That is, it's not a cause
of engine stoppage, but rather it's a cause of not being able to restart the
engine once it's been stopped. Something else needs to stop the engine
first (eg in their testing, they shut down the engine and let it spool down,
and THEN test for "core lockup").
