I changed my mind after a trip away. When trying to use bcmwl_6.20.155 under the generic kernel, the system was very unreliable and often just froze.
I noticed the 6.30.223.30 link you gave me was for the amd46 deb, so I found bcmwl-kernel-source_6.30.223.30+bdcom-0ubuntu3_i386.deb and installed that version (despite the worrying warning it would replace 6.20.155). I was very disappointed to see the install failed with "the usual" GPL-incompatible symbol __rcu_read_unblock. I rebooted to the generic kernel (not really necessary) and dkms status showed the new module had been added already. I ran a dkms install against only the generic kernel and that worked fine. After rebooting, the wifi is working, although I haven't been using it long enough to comment on its stability. I feel this is progress. Even though I haven't moved forward, I've learnt a lot and am now running the latest source. I think I will try making an 0010 patch file for the low latecy changes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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'] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1156138/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
