We are still seeing what seems to be Via PCI corruption when using HPT370 on Abit-KT7-RAID. This is pretty high load (stream read/write two disks in parallel.) It appears as 90-160 byte disk corruption.
It has been reproduced on 2.2.18pre19 + ide, 2.2.20+ide and 2.4.15.
We now seem to have found a BIOS setting that cures this for 2.2.20+ide. The weird thing is that if we boot 2.2.21pre2+ide (pre2 includes the 2.4 backported VIA fixes), the corruption occurs.
We'll try to diff lspci -vvxxx outputs and post a more detailed report shortly.
