Ok, I am happy to say, this response is from the new system.
Sure enough, when reboot, same as initial. Entering LUKS password, causes the system to reboot.
Proceeded to systematically add/remove one at a time.
- loglvl=all (not that I thought these would change anything TBH)
- guest_loglvl=all (not that I thought these would change anything TBH)
- vga=,keep
- noreboot=1
- console=hvc0
- earlyprintk=xen
- plymouth.enable=0
- panic=0
- plymouth.ignore-serial-consoles
- rhgb
- quiet
- qubes.skip_autostart
Only entry that made a difference was “qubes.skip_autostart”, resulting in success.
So thank you all for your time and assistance.
Now, time for my lessons to truly start. I am eager to learn, some may even say enthusiastic.
