  KERNEL: assertion (dev->qdisc_list == NULL) failed at
  net/sched/sch_generic.c(530)

Crap, I think I know what made this start happening. 


Wait, David do you have CONFIG_NET_SCHED enabled in your
config?


No ...


Qdiscs don't get unlinked in qdisc_destroy() unless that config
is enabled.  If you have it off, that explains the bug and the
fix is obvious.


Well, obvious to people who know that part of the stack ... :)
