MSR__EE flag cause problem

Hi, Greetings,

I am porting PPCBoot-1.1.5 to a PPC852 board. When PPCboot executes this
statement

       set_msr(get_msr() | MSR_EE);

in "interrupt_init()" which located at "cpu/mpc8xx/interrupts.c", the
console will display random characters.
But if I get rid of MSR_EE, that is "set_msr(get_msr());", then PPCBoot will
go on and display prompt.

I am a newbie for 8xx. What should I do?

BR,
Fred
