    SubjectRe: Unable to open an initial console (on SMP machine)
    ok, here are some more details:

    NO, i do not use devfs.
    thre is no problem at boot time. /dev directory is where it was supposed
    to be. /sbin/ /etc and everything else is OK.
    nothing is wrong with /dev directory. everything else WORKS.

    just that /dev/console /dev/ttyX and /dev/ttyXX and /dev/vcs* stop
    working:

    this is what i geT:
    root@k:~# cat /dev/console
    cat: /dev/console: No such device
    root@k:~# cat /dev/tty1
    cat: /dev/tty1: No such device
    root@k:~# cat /dev/vcs1
    cat: /dev/vcs1: No such device or address

    what amuse me is that i get different responses ... :-)

    also, as far as i can see the major/minor IS ok ... (see below)

    -----------------------------------------
    /proc/devices
    /proc/tty/drivers

    /proc/devices is missing one line, the last one:
    "unknown /dev/vc/%d 4 1-63 console"


    --------------------------------------------

    root@k:~# cat /proc/devices
