[Bug 1451789] Re: bcmwl causes system freeze

 

Thanks for your feedback, Ralph - much appreciated!

I've found a solution for this bug. When research recent changes to the
WL module source code, I came across a Fedora patch for kernel versions
3.18 and later (https://gist.github.com/hobarrera/ac0e6225210ac5bb13f6
#file-broadcom-sta-6-30-223-248-linux-3-18-null-pointer-crash-patch).
After incorporating this patch in the DKMS hierarchy for the affected
kernels (see above), the module builds and works OK.

I attach the corresponding patch file - please incorporate this fix in
the bcmwl package asap (and don't forget to adjust dkms.conf accordingly
:-).
