Created attachment 1458769 [details] dmesg, lspci and lsmod output when booting FC28 with kernel 4.16.15 and 4.17.3-200 Description of problem: After kernel upgrade from 4.16.15-300.fc28.x86_64 to 4.17 wi-fi did not work anymore. Apparently the problem is related to the kernel. Booting with kernel 4.16.15-300 dmesg provides: "eth0: Broadcom BCM4315 802.11 Hybrid Wireless Controller 6.30.223.271 (r587334)" lspci provides: "0c:00.0 Network controller [0280]: Broadcom Limited BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)" Booting with kernel 4.17.xx eth0: Broadcom BCM4315 is not reported in dmesg output; instead, lspci correctly provides: "Network controller [0280]: Broadcom Limited BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)" Attached you may find the file broadcom_wifi_prblem.txt reporting the output of dmesg, lspci and lsmod generated by booting with kernel versions 4.16.15-300 and 4.17.3-200. Wi-fi is not working with any so far distributed FC28 kernel version 4.17.xx. Version-Release number of selected component (if applicable): kernel-4.17.xx-xxx.fc28.x86_64 How reproducible: Booting with last kernel provided by FC28 and with a PC/laptop wifi by Broadcom BCM4312 wifi Steps to Reproduce: 1. Select PC or laptop with Broadcom BCM4312 wifi 2. Install FC28 3. Upgrade FC28 untill kernel 4.17.xx is installed on the PC Actual results: kernel 4.16.xx provides wifi kernel 4.17.xx provides wifi Expected results: kernel 4.16.xx provides wifi kernel 4.17.xx does not provides wifi Additional info: dmesg, lspci, and lsmod added in attachment

All packages are from FC28 repository, and in particular broadcom-wl-6.30.223.271-6.fc28.noarch. I have no third party rpms installed in the laptop. Does it mean that it is not a supported Fedora driver, since it comes from RPMfusion nonfree branch? May you tell me where I have to provide the information about this bug related to RPMfusion/nonfree?
