Oh, no, of course not.  The most important thing is
if it works for you and fixes your problem and makes
your customers happy (or you if you're a customer).

Nah, maybe a couple of misunderstandings (email tends to
do that), but it's all good.

I think it would've been so much better for everyone if
the RAID vendor had simply fixed their code to not
set VALID when INFORMATION is not valid (spec behaviour).
Since the bug lies in their code, that would've been
the proper course of action.  Instead, every other OS
which uses that RAID HW would have to adjust to this
RAID FW bug (if they haven't already).  Oh, well.
