Can the Skymaster S3132, based on Sil3132, (http://umart.net/au/product_info.php?cPath=21_211&products_id=106108) do 64 bit DMA on Linux? If so, I'm happy to buy that to isolate whether the current problem is limited to SB600 SATA controller alone on AMD690G chipset. It'd be nice if somebody from AMD/ATI could confirm the 64 bit DMA capability of SB600 SATA controller. (I observe a few AMD/ATI folks have been submitting a few patches on LKML lately, so who knows.) Thanks PS: FWIW, SB600 with your ahci fix has been working fine for the past week. Thank you for that.
