Ouch, indeed.

And tty3 displays fine, right?

OK.

I see.  Could you boot the 1.1.0rc2 again and send us the
/var/log/messages file?  (You can either do “herd start ssh-daemon” in
the image or run scp right from there, once networking is up, which
means you have to go to the networking dialog of the installer.)

Florian, could it be uvesafb messing with the graphics card?

Thanks a lot for testing and reporting back!

Ludo’.
