Bcmwl-kernel-source doesn't compile against 4.0

[rektide de la faye]

With a 4.0 kernel provided by http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-vivid/ , bcmwl-kernel-source fails to compile. /var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/make.log is attached, key problems excerpted below:

/var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/src/wl/sys/wl_cfg80211_hybrid.c: In function ‘wl_cfg80211_get_station’:
/var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/src/wl/sys/wl_cfg80211_hybrid.c:1444:20: error: ‘STATION_INFO_TX_BITRATE’ undeclared (first use in this function)
   sinfo->filled |= STATION_INFO_TX_BITRATE;

/var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/src/wl/sys/wl_cfg80211_hybrid.c:1444:20: note: each undeclared identifier is reported only once for each function it appears in
/var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/src/wl/sys/wl_cfg80211_hybrid.c:1457:20: error: ‘STATION_INFO_SIGNAL’ undeclared (first use in this function)
   sinfo->filled |= STATION_INFO_SIGNAL;

The need to run a 4.0 kernel is because the 3.19.0 kernel in Vivid will corrupt and fail on a btrfs system. Either 3.19.5 or 4.0 are required to avoid this corruption: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1445252

Hello,
The bcmwl 6.30.223.141 kernel module couldn't build during upgrading from kernel 3.13 to 4.0.4. (the installation is looking for 6.30.223.248 which I do not use). The error messages pop up during the installation of the dpkg of the .deb files for kernel 4.0.4. Actually there are error messages for all the proprietary packages, i.e. the bc43xx STA 6.30.223.14 driver and the driver for nvidia-331 (I file a separate bug report for that one).

I have tried to prevent those complications by priorly installing the build-essential package, but it did not help. Would it change something if I was unselecting the two proprietary packages from the Software admin prior to installing the new kernel, and then reinstalling after rebooting under the new kernel ?

Meanwhile, what would be the most recent stable linux kernel allowing to keep my proprietary modules ? Thank you !

Hello,
I could have my wireless connection on Acer Aspire V3-471G with the card BCM43228 all in good order after upgrading from Trusty Thar to kernel Wily 4.0.4 by installing the package bcmwl - 6.30.223.248+bdcom-0ubuntu3.

To achieve this, I downloaded http://launchpadlibrarian.net/206246268/bcmwl-kernel-source_6.30.223.248%2Bbdcom-0ubuntu3_amd64.deb and used the command dpkg in the Terminal to build the module on my machine.

Thank you !
