I have an NXP iMX8 system based on a SMARC SoM module from Embedian
which was shipped with Debian 11.
I have successfully used debootstrap to make a Devuan 4.0 system to get
rid of systemd and put the ath10k firmware in /lib/firmware for the wifi
card but now the system hangs for around 2 minutes before the card's
firmware is loaded after which everything works as expected.

The "iw list" command does not see anything, until the messages at BOOT+126.
I don't know whether the regulatory.db error is relevant, or why it
happens as regulatory.db is already in /lib/firmware. (I didn't put it
there.)
