Hi Tomasz,

As I said earlier, such errors are usually related to errors in boot parameters, but your kernel cmdline looks perfectly fine, so unless there's something really odd happening, I can't see this being at fault.
Another (rather unlikely, but I'll still mention it just in case) reason could be that you're using igb_uio module that is really old (I don't remember when igb_uio gained IOMMU support, probably 1.4.x), which is why I asked about DPDK version, but since you're using 1.6.0 you should be fine.
Other than that, I'm afraid I can't think of any reasons why this could be happening. Did you try this on another board with the same OS?
Best regards,
Anatoly Burakov
