I saw the WARN_ON_ONCE hit below on 3.9.0+ (+ hacks)

Were you using VLANs?
No.
I'll be happy to add more debugging if someone has suggestions.
compat = cfg80211_chandef_compatible(
&sdata->vif.bss_conf.chandef, compat);
if (!compat)
break;
}
rcu_read_unlock();
if (WARN_ON_ONCE(!compat))
return;
Might be helpful to know whether chandef_compatible() returned NULL, or
if the loop simply never found an interface with a matching pointer.
Ok, I'll add this.
Probably un-related, but the system usually crashes shortly after. With
memory debugging enabled, it appears to be relayfs and/or ath9k accessing
freed memory.
I'm digging into that one first on an un-hacked kernel..then will
get back to this warning...
Thanks,
