I can't think of any good reason for it /not/ to support 3-disk
RAID6, as there is nothing in the algorithms to hinder it.
I've a vague recollection of Peter Anvin saying the implementation is
optimised in such a way that it won't work.
Okay, optimised implementation is a good reason for not supporting it!
I only know the theory, I haven't studied the implementation well enough
