Re: Unable to open an initial console (on SMP machine)

[Doru Petrescu]

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"
