This problem is in no way related to the ELDK, so you are actually
off topic here.  You should ask this question rather on a Linux kernel
or Power Architecture related mailing list instead, for example here:
linux-embedded at vger.kernel.org  or  linuxppc-dev at lists.ozlabs.org

Maybe, maybe not.  We cannot comment on your code without seeing it.

Best regards,
