[opensuse-factory] iwlwifi performance down to 40% with kernel 3.14 or kernel 3.15
Hi, I observed the following: When I upgrade OpenSuSE13.1 to the kernel 3.14 or 3.15 from factory or the kernel-stable repository, the performance of my Intel Advanced-N 6205 using the /lib/firmware/iwlwifi-6000g2a-6.ucode firmware drops from the normally reached 24MBytes/s down to 9MBytes/s. No other change at all to the OpenSuSE13.1 installation, just exchanging the kernel. This has been reproduced on two different computers, both using iwlwifi. The bitrate of ~300Mbits/s shown in wavemon is not affected by this problem. Just the reached throughput is down to 40% of the old performance. Both, OpenSuSE13.1 and OpenSuSE13.1 with tumbleweed show the problem. Anyone else has seen this? Is there a workaround? I don't want to miss the new features of the new kernel but also don't want to miss the high bandwidth....
