Dear saeed,

I patched a board for pci_err_handling. The patch file is given from 
marvell.
And I re-test a module of sata_sil24.

When I connect a disk to a Pex card(sil3132), Pex error is occurred.
Following is error message.

-> PCI express error : irq - 45, Pex number: 1, Interrupt Cause Register 
value: 400

irq-45 is defined as IRQ_PEX1_ERR and the value of 0x400 means fatal error.
This error is occurred after "sil24_qc_issue".
Function of sil24_qc_issue is to write dma addr to PORT_CMD_ACTIVATE 
address.
Therefore, I think it is dma issue, right?

Now I am checking dma setting of a Dev-Board.

Thank you.
