No vga console after upgrading to 2.4.4



  • Hi all, after upgrading to 2.4.4 we are getting no vga console output on Atom J1800 hardware.
    Dmesg output from 2.4.3:

        class      = display
        subclass   = VGA
    

    Setting

    kern.vty=sc
    

    seems to fix the issue.

    The same behaviour is shown by the 2.4.4 live installer with no graphical output after the bootup screen.

    Is anyone else experiencing the same problem?
