Subject: Re: kern/149185: [rum] [panic] panic in rum(4) driver on 8.1-R
Date: Wed, 4 Aug 2010 22:02:35 +0200 (CEST)
Hi!
Regarding the 8.1 if_rum(4) panics... I got a similar one, extracted
a dump and tried to gather some info for someone who knows the code:
The zero divide fault was because (apparently) rate was unitialized,
as is
((struct ieee80211_node *)
m->M_dat.MH.MH_pkthdr.rcvif)->ni_vap->iv_txparms[0]
i.e. struct ieee80211_txparam &vap->iv_txparms[0] in case it matters. [1]
Simply setting rate to something non-zero (I first tried 0xff, then
72 since that was used in station mode) without changing anything
else stopped the panics but as probably to be expected, the wifi
only partly worked, clients frequently disconnected. (I'll put the
patch at the end of the mail. [2])
