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.
