Both command-based and FIS-based switching seem to work just fine. But there is a problem, maybe you could help with ? I've just noticed that, if I unplug/replug the host-side SATA cable on the Sil3726 PM, and *then* "insmod sata_mv", the PM is not found. If I then simply do "rmmod sata_mv ; insmod sata_mv", then the PM is found. This happens with the original hardreset code from Jeff, as well as the updated sata_mv code that I've posted earlier. So it is not anything I've broken (recently :) ). Very strange.. I wonder if it also happens with the Marvell PM, except I don't have one here to test with at the moment. Ever heard of anything strange like that? ??
