On receiving your email 23 hours ago, I set that option in modprobe and rebooted my laptop. It works fine till just now when that bug occurs again when I was just viewing some man-page. Then I have to reboot my laptop to bring network back alive, in order to reply you this email :-) I've attached the lasted systemd journal, it seems a little different from yesterday's dmesg log... Could you take a look at it? And I found that every time I boot up my laptop there is a little line of message like: Nov 04 17:07:36 xenien kernel: iwlwifi 0000:03:00.0: can't disable ASPM; OS doesn't have ASPM control Does it have something to do with the bug? Though this bug only occurs at a frequency of ~1 per day but it's somewhat unexpected and annoying... ;-( Sincere regards. -- wzyboy 2013/11/3 Grumbach, Emmanuel <emmanuel.grumbach@xxxxxxxxx> > > > > Hi, there. > > > > I am encountering some bugs with iwlwifi.ko in Linux 3.11.6. > > > > My laptop is a ThinkPad X240s with Network controller Intel Corporation > > Wireless 7260 (rev 6b).
