So for the sake of this list archives: In addition to the 2x10G Intel X710 NIC there is a 2x1G Intel I350 NIC in this box. Trying with the igb_uio or vfio-pci driver for the 1G NIC had the same results as with the 10G NIC; hard lock-up when using igb_uio and DPDK is reporting no free ports available when using vfio-pci. However with vfio-pci the following syslog message was logged: "Device is ineligible for IOMMU domain attach due to platform RMRR requirement. Contact your platform vendor." After some searching this seems to be an issue with Kernels newer than 3.16 on HPE boxes (e.g. https://forums.lime-technology.com/topic/53049-solved-device-is-ineligible-for-iommu-domain-attach-due-to-platform-rmrr/). Looks like a BIOS setting can solve this issue (https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c04781229&sp4ts.oid=5249566). I have multiple Kernels compiled on this box. I was using 4.13 for some other testing, so I booted into 3.10, recompiled DPDK+Pktgen and both the 10G and 1G NICs are working using the igb_uio driver. I'd like to be a 4.10 kernel as I was testing some features in there separate to DPDK so I will try disabling that BIOS setting and see if this works with the newer Kernel version. The box is remote so I can't do that right away! Many thanks all for your time and help it is greatly appreciated. Cheers, James.
