Hi, I've updated the kernel to 4.18.1 and then followed the instructions (I've checked and 0x6e did not changed) Here is the gdb output: (gdb) l *(ieee80211_regulatory_limit_wmm_params+0x6e) 0x110e is in ieee80211_regulatory_limit_wmm_params (net/mac80211/util.c:1151). 1146 1147 if (sdata->vif.type == NL80211_IFTYPE_AP) 1148 wmm_ac = &rrule->wmm_rule->ap[ac]; 1149 else 1150 wmm_ac = &rrule->wmm_rule->client[ac]; 1151 qparam->cw_min = max_t(u16, qparam->cw_min, wmm_ac->cw_min); 1152 qparam->cw_max = max_t(u16, qparam->cw_max, wmm_ac->cw_max); 1153 qparam->aifs = max_t(u8, qparam->aifs, wmm_ac->aifsn); 1154 qparam->txop = !qparam->txop ? wmm_ac->cot / 32 : 1155 min_t(u16, qparam->txop, wmm_ac->cot / 32); (gdb) 2018-08-14 7:14 GMT+02:00 Stanislaw Gruszka <sgruszka@xxxxxxxxxx>: > On Mon, Aug 13, 2018 at 08:48:17PM +0200, Grzegorz Duszyński wrote: >> Can I help you somehow with this ? > > Enable CONFIG_DEBUG_INFO=y in .config if not done already. > Then do: > > make net/mac80211/util.o > gdb net/mac80211/util.o > l *(ieee80211_regulatory_limit_wmm_params+0x6e) > > and provide output of gdb l command, this should show code > line number where oops occurs. > > Thanks > Stanislaw
