I build it into my custom 4.4.11 kernel with Yocto (Morty release). The regdb.c that was generated with the awk script was incorrect (it matched the output below where the end frequency was replaced by the bandwidth and the bandwidth was 0). I suspect that the awk script used to process db.txt in the linux build processes it differently than the python scripts.

Looking at db.txt there are no spaces around the '-' in the S1G channels. Has anyone else encountered this issue? I didn't see this in my testing against multiple kernel versions. What version are you using? Are you using regulatory.db or regulatory.bin? I only tested regulatory.bin with regdbdump and not by loading it into a kernel, so there could be a problem there that I didn't catch.
