A quick question..

i have been to use succesfully bootloader kernel and ramdisk , but
only on certain serial port speed .

I am facing a data corruption in dowloading kernel+ramdisk image
at higher serial port speed.

if i set my baud speed to 19200 it WORKS FINE.

otherwise at higher serial port speed  the execve of /bin/sh just
hangs and .

also this problem is related to cpu frequency when i make that
lower or higher the behaviour changed unpredicatabley.

somebody pointed for skew problem woth sdram at higher cpu
frequency.

any body has more here to add...
