8250 serial driver on MPC8272ADS board

[Landau, Bracha]

I am running linux kernel 2.6.13 on a MPC8272ADS board. When I compile the 
kernel with the 8250 serial driver, the kernel crashes when loading it. It 
crashes also if compiled as a module and insmod'ed later.
Has anyone had experience with this?
Thanks,
Bracha
