FYI, i386 party's kernel_thread function calls do_fork directly, 
however, do_fork is called via syscall trap(clone syscall) in powerpc.
So, this difference may be taken place.

IMHO, from this point of view, the real fix for this problem is change 
the way to implement kernel_thread function of PowerPC like as other 
architecture does.
