The IMQ-patch will not longer work against Kernel 6.12.59/6.17.9. It was running till 6.12.58/6.17.8. The problem come from the following Kernel-Patch: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/net/sched?h=v6.12.59&id=4d8b5fe1a401c63a39dc1d37ea1f8707e09a53ed Someone here what can solve this?
