Hi Ray,
It seems that i got same issue with Qubes 4.0 final, Lenovo X1 Carbon I5 vPro 8GB RAM.
After this messages appear, the Screen with the "Q" shows up loading bar filled about 1/5 full and stucked there.
Hope this Problem got some attention, and anyone got a solution or reason why this is happening. Maybe you have already solved it and will let me know how?
If not, sorry that i dont have a solution know, but i will work on get this done.
Cheers,
Jonny
