Subject: CPM2 UARTs: Won't work under low (<= 1200BD) baudrates?

Hello, guys,
I found that MPC8270 CPM UARTs, both SMCs and SCCs won't work under low baudrate.
Under 2400 baud or above the UARTs work fine, but once the baudrate set to 1200 or below, there is NO data can be sent out or received even programed to do so.
I am using Linux kernel 2.6.15 (from Denx ELDK4.0).
Can anybody help on this? Thanks in advance.
David
