The PCI ID parsing in the driver has a pattern matching algorithm that will
catch the card if there is no explicit entry for it. Thus, it'll most
likely be handled here:
{
ID_AIC7899 & ID_9005_GENERIC_MASK,
ID_9005_GENERIC_MASK,
"Adaptec aic7899 Ultra160 SCSI adapter",
ahc_aic7899_setup
},
This hasn't changed since 4.6 and isn't the problem. The pciconf and
dmesg that you posted show that the PCI ID's for your 39160 aren't even
getting probed by the OS. I imagine that this card is the only card
consuming a PCI slot, with everything else being on the motherboard, yes?
If so, there could be a problem where the PCI bridge that controls the
slots isn't being probed correctly. That's why it would be nice to see
the dmsg/pciconf from 4.6.
