I've heard the theory that you are better off matching a Silicon Image
port multiplier with a Silicon Image controller (e.g. 3132 or 3124),
but with no data to back it up.  For me, the Sil3726 pm seems to work as
well with JMB363 (achi(4)) controller as with Sil3132 (siis(4)).

My theory is that as long as everything is working normally,
it works fine.  But if you get some glitch (caused by hardware,
firmware, whatever), the recovery may not be as smooth as it
should be, or it may not recover at all.

Anyone have a way to inject various SATA faults on demand?

BTW, would the -drivers list be a better place to discuss this?
