MCF52259: Software Reset hangs

I want to perform a software reset with a MCF52259 using following code:
After this command the coldfire "hangs": It does not restart and there is even no reaction on a further hardware reset. Just disconnecting the power supply reactivates the controller.(
The same command works with a MCF52211.)

I am using a M52259DEMOMCU Board for this test.

I have also tryed to perform a reset using the Backup Watchdog Timer - with the same result.

Any ideas?
