Yeah, it is the sil4726 virtual device which is really crappy as an ATA device. About the fix, I thought PMP support would fix it but the controller on P5W-DH doesn't support PMP. It can only talk to the virtual device or the device attached to the first port depending on how the PMP chip is configured. It seems we'll have to blacklist the mainboard and skip or use modified reset sequence on the affected port, so that's why the fix was delayed. I'm currently on the road but I'll look into it when I get back (next week).
