Ok. I assume this only happens when loosing the connection and trying to re-associate. At least that is the only possible scenario I can think of where a timeout for mgmt frames is involved. Probably we aren't bumping a refcount correctly or something. Actually that sounds rather plausible as it panics exactly when trying to access ni which should, for a station, always point to iv_bss, which can in turn be free'd almost unconditionally if someone's telling net80211 to associate to another (or even the same) network. Hmm.. tracing refcount it is. Were you running wpa_supplicant at that point? Any messages before the panic happened? -- Bernhard _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
