Hello, Thanks for reporting this issue with details. Reading your issue description and crash logs, there seems that you encountered an already reported problem (https://bugzilla.rpmfusion.org/show_bug.cgi?id=2721). So if you don't mind, I'll tag this bug as duplicate of bug2721, and I invite you to follow it. As I already mention it in this thread, this bug is not so easy to catch (for me at least). I've already tried some trivial quick fixes, but with no luck. The problem seems to be buried in the binary "blob" of the Broadcom STA driver (wlc_dotxstatus function), and there is probably something to do from the sources provided with it, but for the moment, I need a little bit of time to study more precisely where it could be possible to do something. Feel free to provide any feedback you think useful about this bug. Cordially, -- NVieville Yes please Nicolas, tag this as a duplicate of bug 2721. I will follow 2721 now and try to contribute if I can Many thanks for your commitment to finding a solution Regards John |
