console=ttyS* affects booting ...

["ashish anand" <ashish_ibm@rediffmail.com>]

Hello,

I have the following problems with kernel recently ported for 
IDT334 big endian.
for ramdisk image i am using big endian debian( namely root.bin) 
initrd.

1> my kernel port for mips IDT334 board boots fine till it tries 
to
open /dev/console..there it simply hangs....no message

2>i am downloading kernel image through serial link (kermit on 
/dev/ttyS0) with bps 1152008n .
I am mentioning kernel command line like root=/dev/ram 
console=ttyS0,1152008 init=/bin/sh.

now after console_init() in init/main.c i get only junk characters 
in my kermit screen..
if i Do not mention console=ttyS0,* it goes fine till opening of 
/dev/console..

if i specify console=ttyS1 in my kernel command line , booting get 
considerably slow..

i don't understand why specifying console=ttyS0,115200 results in 
junk
characters in kermit screen..?

what is wrong going here?

3> just to mention in my .config file
CONFIG_DEVFS_FS
CONFIG_DEVFS_MOUNT options are set..

4>if i try to open /dev/ttyS0 or /dev/ttyS1 in main.c it says file 
doesn't exist (errno 2)
and goes further , there if i try to execve /bin/sh ( just for 
testing purpose)
i get o/p like..and then it hangs.

but if i do "mount -o loop ramdisk /mnt" and check for ttyS* i can 
see these files.

if i comment CONFIG_DEVFS_FS and CONFIG_DEVFS_MOUNT options in 
.config files and try opening
/dev/ttyS0 or /dev/ttyS1 it simply hangs.

I need a hint to go forward.
