Hi Marius, I've been using the patched driver and have moved more than 500 gigs of data on the disk drive attached to the ata-marvell controller. Can you incorporate your patch into the 8.0 BETA and 7.X stable? It seems a very stable, well-performing driver. It has worked flawlessly during the moves of enormous data backup and forth between the built in fibre-channel drives and the ata-marvell attached Hitachi drive. I wish I could say the same thing regarding the Sil3512. I still haven't been able to go any where with that.
