Another feedback. After rebuilding package bcmwl-kernel-source from source as a backport from Bionic 18.04 I have no error on building dkms for linux kernel 4.15, as expected.
Although I still have errors on broadcom-sta for the same reason. So I will rebuild from source as a backport from Bionic 18.04 and check whether it works. https://launchpad.net/ubuntu/+source/broadcom-sta broadcom-sta (6.30.223.271-8) unstable; urgency=low [ Roger Shimizu ] * debian/patches: - Added 20-linux414.patch, and 21-linux415.patch to support Linux kernel 4.15 (Thanks to Gerardo Esteban Malazdrewicz, closes: #885885) - Fix typo in 14-rdtscl.patch [ Eduard Bloch ] * Dropped extra CHANGELOG file (ancient documentation) * Standard version update to 4.1.3 (added lintian override to broadcom-sta-source since debhelper is used on purpose therein) -- Eduard Bloch <bl...@debian.org> Tue, 13 Feb 2018 21:45:18 +0100 So there is specific patches for linux kernel 4.15 and 4.14, available since mid February. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760108 Title: Broadcom B43 Wireless Driver Not Functional after Update to Linux Kernel 4.15 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1760108/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
