There was a thread about this in December, on blfs-dev, starting at http://lists.linuxfromscratch.org/pipermail/blfs-dev/2018-December/035267.html You can read it all, but here is a brief summary of what _I_ think the main points were: 1. This was a result of changes in, or backported to, linux-4.14. 2. If the wifi is working, despite the message, then fine. If not, install firmware for your atheros, and perhaps for bluetooth (and probably build them as modules). 3. My understanding is that many people can still connect to wifi without installing regulatory.db. I think that was true for Bruce (USA) and it seems to be true for me (GB) - I really must get back to tuning the kernel on my laptop, but this is way down my list of things to look at there. I can see that I have things like: Feb 25 15:41:52 terror kernel: [ 4.080805] cfg80211: Loading compiled-in X.509 certificates for regulatory database Feb 25 15:41:52 terror kernel: [ 4.083343] cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7' Feb 25 15:41:52 terror kernel: [ 4.083499] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2 Feb 25 15:41:52 terror kernel: [ 4.083500] cfg80211: failed to load regulatory.db and similar later on, but wifi is working (wpa_supplicant). ĸen -- It is said that there are two great unsolved problems in computer science: naming, cache invalidation, and off-by-one errors. -- Ben Bullock -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
