You write "processor is stuck" - this is about impossible.  How
exactly did you determine that the processor was "stuck"?  Dd you use
any specific hardware toold to get such information from the CPU?

Or do you just mean that the _system_ does not respond any longer?
Note that this is a fundamentally different thing - the processe may
well be still executing code, and only the communication link is
broken somewhere (say, the console drvier not working correctly).

Where exactly is this 2.6.39 kernel code coming from - and why are you
using such ancient code?   Why don;t you just run a recent (v3.4 or
so) mainline kernel?

Did you rebuild the device tree blob, too?  And did you try the
default kernel configuration that comes with the mainline code
instead?


Also please note that none of your questions are in any way ELDK
related - you are off topic here.  Yiu have much better chances for
getting help on a PPC Linux related mailing list, say
linuxppc-dev at lists.ozlabs.org
