problem in kernel with Stty initialisation

Hello everybody

I am slowly going further with my FADS860T board, and now I have a ppcboot up and running.

I am feeding it with the kernel from denx (2.4.4 07 23 ) and it boots properly until ttyS initialisation where it tryes to access forbidden memory.
I have modified the source to skip that initialisation, and except that, the kerrnel is booting OK.
The problem is that I need the ttyS for my console :-)

the exact output is Oops kernel access of bad area, sig 11 generated by line 417 : return inb(info->port + offset); called by line 3635 : scratch = serial_inp(info, UART_IER);

the Oops is here with the three ttyS.

Is this a known bug ?
did I do something wrong in the config ???
the serial port works well under ppc boot, I use a baud rate of 115200, and the printk messages are output correctly on ttyS1.

thx

Jeremy
