No, it's a limitation of the Promise BIOS on the cards, it will only
detect a maximum of 8 drives. I had a quick convo with tech support
from Promise over this and they told me they don't support more than
one card in a machine in any case. (Which is odd given they advertise
the ability to RAID-5 across 2 cards!)

I'd really consider the PSU. I had all sorts of weird problems with my
promise SATA150 TX2plus until I replaced the PSU. Apparently it doesn't
suffice to supply _enough_ power.
I've since setup the machine so only the motherboard and boot drive are
powered from the system PSU and the 12 SATA drives are powered from a
separate PSU.
Since the machine has previously been running with 8 drives fine on just
the system PSU, I feel confident saying power supply has nothing to do
with my problems.
