** Description changed: I was upgrading my Ubuntu Xenial 16.04 from linux-hwe kernel 4.13.0-38 to linux-hwe-edge 4.15.0-13. After reboot my Broadcom network adapter (requiring package firmware-b43-installer) is not recognized by the new kernel 4.15.0-13. Running the lspci command lists the device as 'UNCLAIMED' in linux kernel 4.15. $ lspci [...] *-pci:4 description: PCI bridge product: Intel Corporation vendor: Intel Corporation physical id: 1c bus info: pci@0000:00:1c.0 version: f0 width: 32 bits clock: 33MHz capabilities: pci pciexpress msi pm normal_decode bus_master cap_list configuration: driver=pcieport resources: irq:123 memory:ef500000-ef5fffff *-network UNCLAIMED description: Network controller product: BCM4331 802.11a/b/g/n vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:05:00.0 version: 02 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress cap_list configuration: latency=0 resources: memory:ef500000-ef503fff [...] $ The lspci -vv -pci:4 commands with the relevant devices are shown below. $ lspci -vv -pci:4 [...] 05:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02) Subsystem: Apple Inc.
