Can you try if by chance this code adapted nvme(4) changes anything on your system? http://www.netbsd.org/~jdolecek/ahcisata_msixoff.diff ahcisata(4) works for me on two different computers in MSI mode. I don't have any ahcisata device which supports MSI-X, but it is working on Cavium which has MSI-X. Perhaps some different BAR wierdness than Cavium, or simply the boards using MSI-X should use the "cavium" BAR? So another thing to try would be to make ahci_pci_abar() return AHCI_PCI_ABAR_CAVIUM always and see if it changes things. Also you can try rev 1.44 of ahcisata_pci.c with AHCISATA_DISABLE_MSIX to see if it works if forced to MSI only. I wonder whether there is something we still need to adjust during general initialization, I see this on my hardware: re(4) - on my system works when attached either MSI or MSI-X nvme(4) - on my system works only when attached via MSI-X (regardless of the PCI_CAP_MSIX), doesn't work when forced to MSI ahcisata(4) works in MSI on my system, as MSI-X for skrll@, MSI-X doesn't work for you Jaromir
