>- reboot with complete shutdown for a couple of minutes
Question,, is this the shutdown from HOLDING pwr button for 15+ seconds? (for me, 20+sec),
for a COMPLETE shutdown?
Did you avoid starting X, at dm (sddm, ldm,whatever) DON'T login, switch to vt and login root?
You could try single mode, add "1" (no quotes) to kernel cmd line in extlinux.conf,
if successful login will be text mode in vt1
(if boot.txt/boot.scr need to recompile scr, with uEnv maybe just in that)
