Looks like it's a compatibility issue with old kernels. Could you please check if the latest commit in the github repo fixes this? :) The explanation, copied from that commit: > The qdisc stats dumping was changed in 4.8 (by commit > edb09eb17ed89eaa82a52dd306beac93e292b485) to be lockless and moving the > responsibility for taking the qdisc root lock into the qdisc itself.
