Yes, c7de2cf053420d63bac85133469c965d4b1083e1 was supposed
to fix some issues ...

You could backport 64153ce0a7b61b2a
("net_sched: htb: do not setup default rate estimators"),
unless you desperately want these rate estimators...
This a kernel based on 3.10. We believe the lockups coincide with
removing/readding qdiscs.

We are seeing a number of softlockups occurring with HTB upon removing
the qdisc. We are still attempting to repro the exact circumstances,
however looking at the code I'm very suspicious of this block in
net_tx_action and its interaction with dev_deactivate (called through
tc_modify_qdisc):
