UART problem on MPC8272ADS

Hi!
Do anyone have 2-nd UART port working on MPC8272ADS?
The target boots OK via both UARTs as console, but any attempt to
transmit/receive data via the other port have failed.
A quick lookup results that ...init_scc is called only in `console`
case. After addition of this call to the cpm_uart_startup (just for
instance) transmit from the target occur, but with only half of data. I
tried various pin settings including working combinations from the old
uart driver but with the same result.
I guess that 8xx that are also handled by this driver may behave
likewise, so any information whether cpm_uart driver works well (or
not) on 8xx is also valuable.
Any ideas how to solve this or concerning possible reasons of such
behavior are greatly appreciated.
