Anyway, I have put: diff --git a/drivers/net/wireless/iwlegacy/iwl-3945-rs.c b/drivers/net/wireless/iwlegacy/iwl-3945-rs.c index 8faeaf2..9221ed4 100644 --- a/drivers/net/wireless/iwlegacy/iwl-3945-rs.c +++ b/drivers/net/wireless/iwlegacy/iwl-3945-rs.c @@ -432,6 +432,7 @@ static void iwl3945_rs_free_sta(void *iwl_priv, struct ieee80211_sta *sta, * to use iwl_priv to print out debugging) since it may not be fully * initialized at this point. */ + printk("XXX: deleting time: %x\n", rs_sta->rate_scale_flush.base); del_timer_sync(&rs_sta->rate_scale_flush); } And the timer base is really NULL when the issue happens.

Yes, it seems to be sufficient to suspend to RAM while associated and turn off the AP before waking up the machine. I wasn't able to reproduce just by turning of the AP while associated without suspend. > If so I'll try to reproduce it locally, otherwise I'll review related > code to find reason of that problem. > > Thanks > Stanislaw Thanks -- Michal Hocko SUSE Labs SUSE LINUX s.r.o.
