Or at least latest 5.15 stable, 5.15.25 is a bit old and is missing lots of fixes. And 5.19 is not even a LTS so wouldn't have many fixes. Ideally if possible testing bpf tree would be the most helpful. https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git/ I believe we fixed a similar bug already so hoping this is just hitting an already fixed bug. But, would be best to confirm thanks. Thanks, John
