Applying patch-4.14.77-78 didn't fix it. Test command:    tc qdisc add dev eth0 root handle 1: hfsc default fffd Kernel answer:    RTNETLINK answers: Numerical result out of range I have identified the problematic sub-patch out of patch-4.14.76-77 to be the problem: diff --git a/net/sched/sch_api.c b/net/sched/sch_api.c index 22bc6fc48311..cd69aa067543 100644 Without this small patch the above "tc qdisc" command works like a charm. Maybe someone can have a look at it. Best regards, Toni
