Following a full BIOS / firmware update on this NUC (which was 5 years
out of date), I have had a stable kernel 5.3.0-46 on the system for up
to 8 hours a day for most of a week. My guess therefore is that a
feature update in the kernel had been tripping a previously fixed BIOS

Intermittent hangs on boot Ubu
Public bug reported:
Hello,
I see occasional hangs on boot. The hangs occur after entering the LUKS
decryption password for the root filesystem, and before the login screen is
displayed. The "/boot" filesystem is not encrypted, so the initramfs is
loading fine etc. The hangs are intermittent
Update: i tried again 20.04 live, and, with kernel 5.4.0-26, wifi seems to work
alright.
So i installed 5.4.0-26 (i believe it was already replaced by -28 upon
installation), but by doing so the wifi HW isn't even recognized, with dmesg
looking for microcode. I'll keep investigating how does 20.
I am having trouble loading the rtl8723bs firmware for a 5.5 kernel on
AntiX 19, (a Debian 10 sans systemd/Gnome). This bug on a 20.04
