>Description:
>From dmesg:

viaide3 at pci8 dev 5 function 0
viaide3: NVIDIA MCP55 Serial ATA Controller (rev. 0xa3)
viaide3: couldn't map sata regs
viaide4 at pci8 dev 5 function 1
viaide4: NVIDIA MCP55 Serial ATA Controller (rev. 0xa3)
viaide4: couldn't map sata regs

and none of the 4 disks is found..,

after applying the patch below I get:
