what is the device id for this board? can you check lspci ? I dont see it as being one of the supported boards (are you sure it is not PCI-6259)? if it is not in that list [1] It might require a little bit of work to add support... can you share a kernel log? I maintained this subsystem for a little bit but Analogy has been without a true maintainer for too long so if anyone wants to volunteer to pick it up I believe that would be awesome (Philippe raised this same issue on his RFC on the 21/11/2017 btw. maybe it is time to address it?) thanks [1] kernel/drivers/analogy/national_instruments/pcimio.c > I tried different variations in the kernel configuration, two different > kernels and I still end up with the same problem.
