some news about that virtual device ata4 found after googling
this mobo p5wdh have module 975x (ich7r);
there are 3 sata avaliable: sata1, sata3, sata4 to plug hardware.
Sata2 is hired for raid with Sil4723 chipset: this one is identified as ata4 when i'm booting.
So, we need to find a way to blacklist this Sil4723 chipset as an ata device.
At present time, i only can boot if i add irqpoll & noprobe=ata4 in grub
