I built an v4.17-rc6 kernel with CONFIG_IWLWIFI_DEBUG=y and booted with iwlwifi.debug=0x4000. I've attached the dmesg output and kernel config. The crash happens right away, so there's no time to easily run trace-cmd. But if the other stuff still isn't enough, I can try booting with the NetworkManager service disabled, then enabling it at runtime. - Eric
