[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #2 from [email protected] --- Hello! While working with iwfi drivers in Haiku (those drivers are ported from FreeBSD) i founded the bugs, that potentially is FreeBSD specific. iprowifi4965 and iprowifi3945 are affected. May be others. I will describe them on iprowifi4965 code. iwn_tx_done has KASSERT(data->ni != NULL, ("no node")) at beginning that is triggers in some situations. The situation can be: 1) hw interrupt is scheduled 2) iwn_hw_stop is called (and it disables/enables interrupss) node is destroyed here. 3) here we got scheduled (threaded) interrupt that is not actual anymore -> panic In fact, i was thinking it is Haiku specific bug, because of threaded inr handlers. But i found this bug report and it seems the same for me. To reproduce it on Haiku i run floodping to roater while reboot the system. But on FreeBSD i am not sure, what can couse iwn_hw_stop while sending packets... Hope it helps. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "[email protected]"
