Welcome on-board.

Not entirely. It is almost working: too bad as soon as the SATA disks 
are probed, the system is overflowed by a massive interrupt storm.

7-CURRENT with one disk only is able to complete setup (very slowly), 
though the problem is still present (try vmstat -i). 6-STABLE completely 
HANG as per your report. The same does 7-CURRENT with more than one ATA 
channel used: i.e. you can boot if you put two disks on ports SATA1 and 
SATA2 (ata2 master and slave), but it hangs if you try SATA1 and SATA3 
(ata2-master and ata3-master).

Unfortunately there wasn't any ack from interested party (I suspect it 
may be linked to ATA-SATA and/or ACPI routing of IRQ), so I think there 
are no developers in possess of that MB.
