*Hi all,

I want to run full system with O3CPU. When I use single core and two cores,
my simulator run successfully. However I cannot increase cpu number to 4 and
more.

The terminal show:

*Kernel panic - not syncing: Attempted to kill the idle task!*


*I think my problems are the two red lines. I tried to use larger memory
size, but it was not useful.*
*Could you please give me some suggestion.
Thanks in advance.

Shu.*
