Hello, L4 hackers :-)
Always, I'm obliged to you.

I have a question.
When I configured Fiasco.OC containing option which is 'unable multi 
processor support'
, I've succeeded booting (L4 linux + L4/Fiasco) on Freescale 
imx6q_sabre_sd(Cortex-a9).

And, I've configured Fiasco.OC as follows.. , again.
=========================
[*] Enable multi processor support
(4)   Maximal supported number of CPUs (NEW)
[*] Fine-grained CPU time
=========================

But I could not booting it successfully.

It's stop at '*CPU[3]: goes to idle loop*'

What's the problem ?








Log I met is such as....
