I just resumed from suspend to RAM and set up my wireless interface which involved modprobe for iwlwifi[*] (where udev came into play). --- [*] - my script for setting up home wireless connection rmmods iwlwifi, iwlcore mac80211 cfg80211 and then modprobes iwlwifi. It is a relict from the past where I wasn't able to re-establish the connection in some cases (well stupid router which totally confused the driver) without reloading modules. I guess this is no more needed but I was lazy to touch my scripts when they work. -- Michal Hocko SUSE Labs SUSE LINUX s.r.o.
