2013/11/5 wzyboy <wzyboy@xxxxxxxxxx>: > I've been using Linux 3.12 for one day now, no more bugs about > iwlwifi.ko are encountered... Maybe this is fixed in Linux 3.12? Hi, I'm back. This terriable bug occurs again in Linux 3.12. This time I've been prepared for it and wrote down the complete process of its apperance and my reacting, as attached. IMHO they are quite similar with those errors in 3.11... Sincere regards. -- wzyboy
