It has been reported here: https://bugzilla.kernel.org/show_bug.cgi?id=109581 And there is a workaround from Konstantin: https://patchwork.ozlabs.org/patch/803885/ Unfortunately I don't think that is a real fix, we probably need to fix HFSC itself rather than just workaround the qlen==0. It is not trivial since HFSC implementation is not easy to understand. Maybe Jamal knows better than me. Thanks
