Richard,
this board is supported by mainline kernel, can you try latest
version (3.0-rcX)?
I can't find reason of not working. Please advise to me.
Thank you.

Dear saeed,
I tested sata_sil24 driver with 3.0.0-rc6.
At first booting, machine id was not supported in new kernel.
And I replaced id(0x690) of DB-88F6281-BP with 0x20f.
After changing machine id, booting was completed.
I loaded "libata dma=0" and "sata_sil24".
But result was same to before. -> qc timeout(0xec)
does this controller (sil24) works on different platfrom (PC)?
have you tried different disk?
Thank you.

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.
