I have backported the august 42016 release (6.30.223.248+bdcom-0ubuntu9) to Trusty, and that source builds and works fine with the 4.7.2 stock kernel.
It also builds fine with 4.8.15 stock kernel. However, I get an oops when wl.ko is loaded, not in the bcmwl driver itself but in the cfg80211 driver, a null ptr dereference as far as I can see. Does the fix discussed here address that issue too, or is that related to something else? I see that wl.ko is being loaded on another laptop with an Intel wireless board, and there I'm not seeing any kernel oopses. Neither in cfg80211 which is also used by the iwl drivers. -- 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/1595765 Title: Wifi drivers all fail to build [error: ‘IEEE80211_BAND_2GHZ’ undeclared here] Status in bcmwl package in Ubuntu: Confirmed Status in broadcom-sta package in Ubuntu: Confirmed Status in rtl8812au package in Ubuntu: Confirmed Bug description: error update for kernel 4.7 RC 3 ProblemType: Package DistroRelease: elementary 0.4 Package: bcmwl-kernel-source 6.30.223.248+bdcom-0ubuntu8 [origin: Ubuntu] Uname: Linux 4.6.2-040602-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 DKMSKernelVersion: 4.7.0-040700rc3-generic Date: Thu Jun 23 22:03:59 2016 DuplicateSignature: dkms:bcmwl-kernel-source:6.30.223.248+bdcom-0ubuntu8:/var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/src/wl/sys/wl_cfg80211_hybrid.c:237:12: error: ‘IEEE80211_BAND_2GHZ’ undeclared here (not in a function) InstallationDate: Installed on 2016-06-14 (9 days ago) InstallationMedia: elementary OS 0.4 "Loki" - Daily amd64 (20160613) PackageVersion: 6.30.223.248+bdcom-0ubuntu8 RelatedPackageVersions: dpkg 1.18.4ubuntu1.1 apt 1.2.12~ubuntu16.04.1 SourcePackage: bcmwl Title: bcmwl-kernel-source 6.30.223.248+bdcom-0ubuntu8: bcmwl kernel module failed to build UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1595765/+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
