I don't know whether update-initramfs was necessary, but it certainly didn't do any harm!
The low-latency dmesg now shows the wl and cfg80211 modules are being loaded, but there is a problem: [ 24.624284] wl: module license 'MIXED/Proprietary' taints kernel. [ 24.624290] Disabling lock debugging due to kernel taint [ 24.626241] wl: Unknown symbol rcu_read_unlock_special (err 0) The unlnown symbol is the same as in the warning I noticed in the dkms install log, so it is important after all... Also, once the system has booted lsmod does not show the wl module any more, and the eth1 interface does not exist. I will do some research on that symbol in the bcmwl patch. -- 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: Confirmed 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
