Hm, yes, we have seen such a phenomenon.  It was triggered by the fact
that the arch/ppc kernel erroneously tried to use vdso support not
supported in arch/ppc to handle gettimeofday.  The fix should be this
commit

    [POWERPC] Disable vDSO support for ARCH=ppc where it's not

I'll check later why this is not in the ELDK linux tree.

That should not happen and I don't think its a known problem.  I have to
check later what may cause this.

This should also not happen - could you please post a complete log of
the boot procedure including the U-Boot statements to start the kernel?

Thanks
