Yes I have the same problem.
I think I found the origin.
That's because wme_qdiscop_destroy in net/mac80211/wme.c passes a bad
pointer in tcf_destroy_chain.
It requires a struct tcf_proto **fl and not a struct tcf_proto *fl
Here is a patch, I can't test it because my gcc segfaults but I think it
will correct the bug.
