Niltze- Built reiser4 enhanced Linux 4.15.15 wrapped by Debian packaging for kernel 4.15.11 (last I found) modified for GCC6 stretch-backports AMD64. Upon booting kernel in wireless maching, it complained about: platform regulatory.0: firmware: failed to load regulatory.db (-2) [ 12.134223] firmware_class: See https://wiki.debian.org/Firmware for information about missing firmware [ 12.134281] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2 [ 12.134283] cfg80211: failed to load regulatory.db Doing an online search it seems this is a 'feature' of kernels 4.15.x, i.e., below is for Slackware: < https://www.linuxquestions.org/questions/linux-kernel-70/kernel-platform-regulatory-0-direct-firmware-load-for-regulatory-db-failed-with-error-2-a-4175622954/ > Notwithstanding, Debian seems to be lacking relevant files in ~2016 (last/latest) wireless-regdb package. Although I created a repo at Github < https://metztli.github.io/wireless-regdb-metztli/ . there is only a small hack to debian-example in git source for wireless-regdb, from upstream, thus created attached patch for git clone git://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git cd wireless-regdb cat debian-upgraded-regulatory-regdb-for-4.15x.patch | patch -p1 dpkg-buildpackage -F -us -uc -j2 -T binary Generates upgraded wireless-regdb_2018.04.02-1_all.deb ./lib/firmware/ ./lib/firmware/regulatory.db #1} Specifically ./lib/firmware/regulatory.db.p7s #2} Linux 4.15.x needs ./usr/ ./usr/lib/ ./usr/lib/crda/ ./usr/lib/crda/regulatory.bin #3} these upgraded files. ./usr/share/ ./usr/share/doc/ ./usr/share/doc/wireless-regdb/ ./usr/share/doc/wireless-regdb/README ./usr/share/doc/wireless-regdb/changelog.Debian.gz ./usr/share/doc/wireless-regdb/copyright Of course, also apt-get install crda as it is recent from Debian repositories. I built *both* packages (nmu .1 and -1) and made available *without* guarantee to solve your particular relevant issue: https://metztli.it/readOnlyEphemeral/wireless-regdb_2018.04.02-1_all.deb https://metztli.it/readOnlyEphemeral/crda_3.18-1.1_amd64.deb They fix the above wireless regulatory.db issue(s) in my machine.
