I've done a lot of work trying to get the patch to work, including trying to resolve the subsequent problem where the wl.ko module builds but fails to load because rcu_read_unlock_special cannot be used on the current 3.8.0-30-lowlatency kernel. This issue is reported in https://bugs.launchpad.net/ubuntu/+source/linux-lowlatency/+bug/1154036.
Exasperated after digging around and finding far more knowledgeable people than me were stumped, I gave up. I edited my local copy of 0001-MODULE_LICENSE.patch to replace the string "Mixed/Proprietary" with "GPL". The broadcom wireless driver is now working on my system. I look forward to removing the kludge as soon as this bug is fixed properly. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bcmwl in Ubuntu. https://bugs.launchpad.net/bugs/1156138 Title: bcmwl-kernel-source fails to build on lowlatency kernel [FATAL: modpost: GPL-incompatible module wl.ko uses GPL-only symbol '__rcu_read_unlock'] Status in “bcmwl” package in Ubuntu: Triaged Bug description: Ubuntu 13.04 ProblemType: Package DistroRelease: Ubuntu 13.04 Package: bcmwl-kernel-source 6.20.155.1+bdcom-0ubuntu6 ProcVersionSignature: Ubuntu 3.8.0-13.22-generic 3.8.3 Uname: Linux 3.8.0-13-generic i686 NonfreeKernelModules: wl ApportVersion: 2.9.1-0ubuntu1 Architecture: i386 DKMSKernelVersion: 3.8.0-12-lowlatency Date: Sat Mar 16 23:37:03 2013 InstallationDate: Installed on 2013-01-03 (72 days ago) InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release i386 (20121017.2) MarkForUpload: True PackageVersion: 6.20.155.1+bdcom-0ubuntu6 SourcePackage: bcmwl Title: bcmwl-kernel-source 6.20.155.1+bdcom-0ubuntu6: bcmwl kernel module failed to build UpgradeStatus: Upgraded to raring on 2013-03-12 (4 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1156138/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
