Hi, I just pulled out my Marvell 7042 SATA controller here to give it a spin and noticed that it no longer worked (i.e. init segvs when loading from it), etc. 2.6.22 is fine. Bisecting (just the file drivers/ata/sata_mv.c) resulted in bdd4dddee325a7dce3e84cf48201a06aa8508aa4 popping out as the culprit (file version 4537deb5e90b717a725b3d74b58b4bb1d28443d0 is fine). Just for sanity checking: Has anyone else used 7042/6042 with the current mainline driver?
The update was tested extensively on 6042. I have a 7042, but haven't found a compatible PCI slot here.
Hardware config in my case: Highpoint 2310 controller PPC (big endian) WD Raptor disk Works fine with the other controller I've been using (SIL24), and works fine if I revert the driver. It also works fine if I disable the IOMMU. This would point towards either a stale dma mapping, or a missing setup of one. Not being much at home in the SATA drivers I could keep digging but I figured I'd bring it up first in case it rings a bell for someone.
The IOMMU data point is certainly interesting. Nothing jumps out on a re-review of the patch, so keep digging and let us know ;-)
