Do you recall why sata_via doesn't support configuration where SATA_2DEV bit is set in the SATA_PATA_SHARING PCI conf reg? Is it a leftover from the days when libata didn't support mixed PATA/SATA setup? I have a machine which does that and just skipping the test makes it work just fine and there's also a bug report reporting the same problem. It seems some new chipset from via is setting the bit. Thanks. -- tejun
