Title: ubuntu_kernel_selftests:net:udpgro_fwd.sh: udpgso_bench_tx: sendmsg: Connection refused Status in ubuntu-kernel-tests: New Status in linux package in Ubuntu: Incomplete Status in linux source package in Jammy: Confirmed Status in linux source package in Kinetic: Confirmed Bug description: This is from ADT testing (amd64) but I believe I occasionally saw this before.
