[uml-user] UML stops after "Initializing stdio console driver" on SuSE 9.0/Kernel 2.6.4

[Ingo S. <br...@th...>]

Hi all!

I tried to run UML on my SuSE 9.0 with host kernel 2.6.4, which has the
skas3 patch applied and /proc/mm enabled. Other than that it's plain
vanilla.

/usr/src/linux# uname -a    
Linux linux 2.6.4skas3 #11 SMP Tue May 4 00:50:00 CEST 2004 i686
i686 i386 GNU/Linux

/usr/src/linux # grep -i PROC .config 
CONFIG_PROC_MM=y
...

And after that it just exits with return code 0.

I tried searching the mailing list and all I found was two hints: one to
use skas3 (which doesn't seem to cure the problem) and another to check
the following settings:

~/local/usermodelinux/linux-2.6.4$ grep CHAN .config
CONFIG_FD_CHAN=y
CONFIG_NULL_CHAN=y
CONFIG_PORT_CHAN=y
CONFIG_PTY_CHAN=y
CONFIG_TTY_CHAN=y
CONFIG_XTERM_CHAN=y
CONFIG_CON_ZERO_CHAN="fd:0,fd:1"
CONFIG_CON_CHAN="pty"
CONFIG_SSL_CHAN="pty"

The default CONFIG_CON_CHAN="xterm" didn't work either.

Anybody some further ideas?

TIA,
Ingo
