This patch set default values for the FIFO PCI Bus Arbitration to avoid data corruption. The root cause is due to our PCI bus master handling mismatch with the chipset PCI bridge during DMA xfer (write data to the device). The patch is to setup the DMA fifo threshold so that there is no chance for the DMA engine to change protocol. We have seen this problem only on one motherboard.

Patch applied to libata-2.4 and libata-2.6 queues, and will be sent upstream ASAP. Thanks.
One slight problem with your submission: your mailer encoded the plaintext patch using base64 encoding, which makes the patch difficult to review.
The preferred method of submitting patches is pasting them inline. However many Windows mailers will corrupt the whitespace in the patch, or wrap long lines, if you do this.
On Unix, the best way to accomplish this is described at

On Windows, the free (open source) Mozilla Thunderbird or Mozilla Mail applications should correctly attach plaintext patches without encoding them.
Regards,
Jeff
