I am using an on-board Promise controller, and had similar problems when
first setting up this server.
# pciconf -lv | grep -B1 -A3 Promise

What I discovered was that my cables were too long. I had purchased
those round cables in order to reduce air flow restrictions in the case,
but at the time, I could only get 36" cables. After quite a few lost
mirrors, I found out that those cables _should_ be a maximum of 18"
long. I replaced the 36" cables with 18" cables and haven't had a
problem since.
I don't know if this will help you, but it certainly fixed the problems
that I was having.
Good luck.
