I'd be very suspicious of a metastability problem if the results are even
Most of the quirks that get blamed on metastability are just simple
setup/hold errors such that an input to a state machine has different values
at different FFs. The two obvious causes are a longer delay on one path
(more logic, longer routing) or slightly different setup times on the FFs so
a signal gets to both at the same time and meets setup one one but doesn't
the other one.
These are my opinions, not necessarily my employer's. I hate spam.
