kernel 2.6.14 on MPC8272ADS

I'm trying to move to the latest kernel release from linux 2.6.13.4 on =
the MPC8272ADS board.
2.6.13.4 works, but from 2.6.14 and up (I don't know where from 2.6.13.4 =
to 2.6.14 the problem starts) the kernel crashes on bootup with the =
message=20
"Kernel BUG in ppc_sys_init at arch/ppc/syslib/ppc_sys_init.c:131"
Anyone know how to fix this problem?
