So, it confirms that the problem is still present with the latest TW kernel (4.7.x at that time?). One more check just to be sure: add the blacklist of iwlwifi, and confirm that it doesn't hang -- i.e. the problem is in iwlwifi. For example, put the following line to /etc/modprobe.d/99-local.conf blacklist iwlwifi And reboot with oS-42.2 and TW kernels. If the system works fine without iwlwifi, then try to set up kdump to catch the crash. You can use YaST2 kdump module. You'd likely need to put a larger reserved RAM there than suggested, e.g. 256MB lower memory. Once after kdump is set up, reboot again with iwlwifi blacklisted. After login, load iwlwifi module manually % modprobe iwlwifi Then WiFi stack will appear. Continue using it until it reaches to a crash. If kdump doesn't work well, but if you can still do remote-login or such, it'd be helpful. What we inevitably need is the kernel Oops / bug messages. In anyway, please attach the kernel boot messages (the output of dmesg) after loading iwlwifi driver on both 4.4.x and TW kernels.
