File: dmesg
Got some more information on this. It looks like the original patch from kernel 4.3.x did not fix the problem, and that a new patch[1] has been included in kernel 4.4 to resolve the problem. Is there any chance of back porting this patch to fedora kernel 4.3.4 ?

Please test this scratch build with the patch included when it completes and let us know how it works for this issue: http://koji.fedoraproject.org/koji/taskinfo?taskID=12691482 Hi @Josh, -- First, I like to say a great big thanks for going through the trouble of including the patch and building a kernel that I could test with (that actually made my day, I did the victory dance and all that ;)). -- Second, it took me a while to figure out that I had to click on the "Descendants build" to get the generated rpms, so I ended up searching for and installing the wrong kernel packages [1], which of course failed. -- Third, after installing the right packages, my system came up fine and the wireless was working again, which got me doing another dance. -- Fourth, another GREAT BIG THANK YOU, you are SUPER AWESOME. FYI: I am using and testing on fc22 (I could not upgrade to fc 23 cause it would have rendered my system inoperable) [1] http://koji.fedoraproject.org/koji/taskinfo?taskID=12676566 Just in case I was not clear above, the patched kernel http://koji.fedoraproject.org/koji/taskinfo?taskID=12691482 worked Fixed in Kernel 4.3.6-201 Thank you for reporting and testing |
