That's the version I'm using in my last reply -- from ppa:canonical-server/server-backports: 33.1-1ubuntu1~backport20.04-202103240925~ubuntu20.04.1 Noticed now, but with the new kernal and rdma-core librdmacm-dev from backports there are some new mlx5_pci errors. Appears to be working OK otherwise though. EAL: Detected 8 lcore(s) EAL: Detected 1 NUMA nodes EAL: Detected static linkage of DPDK EAL: Selected IOVA mode 'VA' EAL: Probing VFIO support...
