Ah, this one goes through platform driver (why do you load istallion and 
stallion drivers?).

8250.c driver changes:
Alan Cox (3):
       serial: Coding style
       serial8250: coding style
       8250: enable rate reporting via termios

Will Newton (1):
       8250.c: support specifying DW APB UARTs in device platform_data

Nothing seems intrusive, but whatever changes in the rest of the serial 
might have caused it. Could you bisect it? I think it would be fast.

git-bisect v2.6.25 v2.6.24 -- drivers/char/ drivers/serial/
