When I try this, I get the call trace below, and the hardware still does not work. FWIW, this is with 4.16.0-3.g2592f12-default from Kernel:stable Here is the call trace after running the following commands: # rmmod iwlwifi cfg80211 # modprobe iwlwifi Apr 09 12:20:09 saturn kernel: cfg80211: Loading compiled-in X.509 certificates for regulatory database Apr 09 12:20:09 saturn kernel: cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7' Apr 09 12:20:09 saturn kernel: Intel(R) Wireless WiFi driver for Linux Apr 09 12:20:09 saturn kernel: Copyright(c) 2003- 2015 Intel Corporation Apr 09 12:20:09 saturn kernel: iwlwifi 0000:06:00.0: loaded firmware version 17.608620.0 op_mode iwlmvm Apr 09 12:20:09 saturn kernel: iwlwifi 0000:06:00.0: Detected Intel(R) Dual Band Wireless AC 3160, REV=0x164 Apr 09 12:20:09 saturn kernel: iwlwifi 0000:06:00.0: hwdev DMA mask = 0x0000000fffffffff, dev_addr = 0x0000000079db6000 Apr 09 12:20:09 saturn kernel: iwlwifi 0000:06:00.0: swiotlb: coherent allocation failed, size=1024 Apr 09 12:20:09 saturn kernel: CPU: 2 PID: 8521 Comm: modprobe Not tainted 4.16.0-3.g2592f12-default #1 openSUSE Tumbleweed (unreleased) Apr 09 12:20:09 saturn kernel: Hardware name: To Be Filled By O.E.M.
