Hello, I've been having problems with Sil 3112 cards I purchased for additional SATA ports resulting in read data corruption, about 3-5 instances over 2 GB of data, 100% reproducible. I tried fiddling with PCI latency timer, underclocking, all sorts of stuff, all no help. I just rebuilt the entire box with the remains of another (went from A7V8X (VIA) to A7N8X (NVidia), new CPU, new RAM, new power supply), thinking the problem was related to the motherboard. The issue followed to the new box. This new motherboard has an onboard Sil 3112 as well. The old onboard was VIA SATA, which did not corrupt anything. The Sil 3112 onboard now does too. I noticed the driver has a request-limit quirk. I tried forcing this on -- same results. I noticed there is a DMA-limiting quirk -- forced on, same result. I can't seem to find a way to make this chipset not corrupt reads. Am I alone? Scipt used to md5sum to find corruption: find $* -type f -print0 | sort -z | xargs -0 md5sum Reproduced on any recent 2.6 kernel version (2.6.18 - 2.6.21).
