Hi,

We're having some trouble with detection of a couple of Sil3124 SATA
controller cards on newer motherboard and processor combos.
Specifically, we're running a Supermicro X9SCM-F motherboard (latest
BIOS) and Intel E3-1220v2 CPU.

What we're seeing:
- Syba Sil3124 PCIe cards are only being detected when installed in PCIe
Slot 4
-- The motherboard documentation shows that this is the only slot
connected to the Intel C202/204 chipset on the motherboard
-- Slots 5, 6, and 7 are connected to the integrated northbridge on the
Ivy Bridge CPU
(there is no slot 1, 2, or 3)

FreeBSD won't detect even a single Sil3124 card installed in PCIe slot
5, 6, or 7.  If we put an Intel Dual-port NIC in either of one of these
slots, it is detected just fine.

I've attached a verbose dmesg.boot from this box running FreeBSD
9.0-RELEASE.  We've also tried 8.1-RELEASE, 8.2-RELEASE, and 9.1-BETA1
with the same results.  Booting with ACPI disabled results in a kernel
panic during the boot process.

I'd greatly appreciate any help or suggestions on this matter. We've
already tried just about every BIOS option on the board.
