Platform type : ppc8540ads platform
Problem hardware type: Promise20268 PCI-ATA card

system,Partition table.
Problem description:
     When I boot my board, the kernel can recognize my Promise20268 card,

SegateHD correctly. but prompt with "lost interrupt" message.
    After boot procedure, the /proc/partitions file shows correct partitions
