Dear list I'm still having trouble with bcm4356 on a Lenovo L460 previously reported here [1] (a Arch Linux bug report including the responsible git commit can also be found here [2]). The last working firmware version was 20170907. With all newer including the latest 20180507 I get [ 6.170608] brcmfmac: brcmf_fw_map_chip_to_name: using brcm/brcmfmac4356-pcie.bin for chip 0x004356(17238) rev 0x000002 [ 6.195769] brcmfmac 0000:03:00.0: Direct firmware load for brcm/brcmfmac4356-pcie.txt failed with error -2 ...
