UART1 problem on AM1808 custom board (with kernel - 2.6.33-rc4)

Hi

I have enabled UART-0 & UART-1 in kernel 2.6.33-rc4 for  AM1808 custom board, and using UART-2 as console.

In application I set following termios parm

           struct termios newtio;
           bzero((void *) &newtio, sizeof(newtio));
           newtio.c_cflag = baudRate | CS8 | CLOCAL | CREAD;
           newtio.c_iflag = IGNPAR;
           newtio.c_oflag = 0;
           newtio.c_lflag = 0;          
           newtio.c_cc[VMIN] = 0;
           newtio.c_cc[VTIME] = 1;
           newtio.c_cflag &= ~CRTSCTS;
           tcflush(DevNode, TCIFLUSH);
           tcsetattr(DevNode, TCSANOW, &newtio);

UART-0 working fine, but incase of UART-1 able to transmit data, but on Rx pin getting random data (random spikes viewed on osci-scope).

Thanks,
