Sounds like PCI not being completely restored. We had to work around some weird ATA issues in FreeBSD with the status register being invalid for quite a while after resume. A retry loop was the solution.
FreeBSD seems to fail in the same way on the same hardware, unfortunately. I'm leaning towards suspecting that we need to be doing something with the contents of the _GTF method, but by the looks of that that requires us to be able to work out which methods correspond to which hardware. Is anyone working on implementing this?
Very interesting. I was hoping to someday have _GTF et al implemented but the ATA knowledge required was above my head. I also strongly suspected that the info published by _GTF would likely be invalid. Does Windows actually use that method or just hardcoded ATA initialization?
