Yet another follow up on my own post...

Update Redoux:

1) Using the amr driver from 7-CURRENT yields same results.  

2) Did some testing playing musical hard drive slots.  IF I do NOT
use slot 1 (# on Tyan Backplane starts w/1) and use the EXACT same raid
config for the mirror usings, e.g. slots 2 & 3, then all works as
normally expected.

So it would seem that Tyan and/or LSI have something Foobarred?  Or
that for some reason FBSD is overwriting directly to disk on slot 1
(i.e. da0) even though it's not technically there?

Bizarre hardware issues.  My raison d'etre...

Best regards,
