Description:
The latest update of the linux firmware (linux-firmware 20171206) broke the wlan on my Lenovo L460. On boot up i get the errormessage: "A start job is running for sys-subsystem-net-devices-wlp3so.device". Further infos in dmesg.txt (at the end of the file). I solved the problem temporary by manually downgrading the linux-firmware package to 20171123. This is the hardware: 03:00.0 Network controller: Broadcom Limited BCM4356 802.11ac Wireless Network Adapter (rev 02) Subsystem: Lenovo BCM4356 802.11ac Wireless Network Adapter Kernel driver in use: brcmfmac Kernel modules: brcmfmac Additional info: * Kernel version: 4.14.5-1 * dmesg.txt Steps to reproduce: Update the Linux firmware to "linux-firmware 20171206" on a Lenovo L460. |

That is, I copied the attached nvram file to /lib/firmware/brcm/brcmfmac4356-pcie.txt and my network controller works with the latest linux-firmware now.
