This the patched version with DMA Boundry fixes. I need a backport as kernel is supported for a specific hardware (Cavium Octeon). This looks somewaht stable on the hardware as compared to 0.5 and 07 which are very unstable and gets struct in middle. I can send those logs if needed. Please note that in PIO mode everything looks OK with this setup. Apreciate your help. Thanks, Narendra Here is the log for 0.25 with DMA bounryfixes.

Thanks. This works in PIO mode hence performance is horrible. I see the udma mode is set to 0 in driver 2.6.14 sata_mv version 0.12. Is is possible to Back port sata_mv from versin 2.6.17 to 2.6.14 to get a stable drive. Please let me know.
