12 years after I created this post, i'm going to post a new screenshot of my new os going crazy!!
(i started recently a new kernel)
This is related to the issue i posted here: viewtopic.php?f=1&t=42446

But the result when not using the framebuffer is fascinating! :D And some how very tidy and clean...
This happens after adding a new print statement (after many of them already added above... and working, but for some reason whatever is the content is causing a that **** to happens...)

Something went wrong implementing Carriage return.
Code:
push rax
push rcx
push rdx
        mov rax, rdi
        sub rax, TEXTBUF_BASE
        mov rcx, 80
        div rcx
        sub rdi, rdx
pop rdx
pop rcx
pop rax


EDIT: adding 'xor rdx,rdx' after the pushes solved the problem.
I will have to look at my previous implementation

I forgot to increment the offset register twice in the video memory and ended setting the color attribute to a character.
