SiI 3114 SATA support (plain disk mode)

Hi

I realize that the ATA/SATA support is evolving and ongoing.  I just 
wanted to know what the current level of support is for the SiI 3114 
SATA controller in -CURRENT.   I want to use it with plain old disks, 
not in any raid mode.

I have a Tyan S2882 dual Opteron board running FreeBSD 5.2-CURRENT 
(updated May 11) running i386 version.  This machine has an Adaptec 
2200S controller with two arrays.  Additionally I have several SATA 
drives I want to use using the built-in SiI 3114 controller.  These are 
for backup and scratch disks, etc.  The machine boots off the 2200S 
controller.

Every time I enable the SiI 3114 controller (in ultra plain disk mode 
if it matters), the controller is detected, but when it goes to detect 
the disks, it hangs up the machine.  ata5-master and then some detect 
stuff and hang.  I will have to go to the data room and reset the BIOS 
to enable the controller and reboot to get the exact message.

I temporarily am using a Maxtor (Promise) PCI SATA controller card to 
get two of the disks running but this is not a long term solution since 
the card is not a low profile card and this is a 2U rack and I cannot 
close the lid completely with the Maxtor.

Any info on the status of SiI 3114 support in i386 FreeBSD (Tyan S2882) 
would be appreciated.

Thanks
Chad
