dpdk igb_uio driver not loading

Question

I am trying to load the igb_uio driver into my kernel, and I am getting the error:

insmod: ERROR: could not insert module igb_uio.ko: Invalid module format

I have been sleuthing around and am finding generally the answer to this is usually a kernel version mismatch. I have checked my kernel version with uname -r and it matches the kernel version from modinfo igb_ui.ko

Any ideas what else might be going on? Thanks, Adam
