Hello Hauke, thanks for the patch. I tried it on my Asus WL-520GU with BCM5354 SoC. As expected, the warning goes away. But the router still becomes unstable as soon as I start WIFI. I tried both the 666.2 and the 410.2160 firmware, but the results are the same. As soon as WIFI starts, the system becomes so unresponsive that it seems like it crashed. However, a previously started dmesg in a "while true" loop still works for some time, albeit it responds very slowly. After a few minutes the router will reset. With 666.2, the oom-killer kicks in, too. I didn't see this in the dmesg with the 410.2160 firmware, but it may just be that the dmesg process died. I attached the dmesg output for both cases. I'd be happy to provide more help in debugging and fixing this issue. -- CU, Christian Klein
