Nothing jumps out from the logs.  Thanks for the pointer about ppc. 
I'll hunt down some PPC hardware and see if I can reproduce/fix.  Could 
you be more specific about which ppc (32 or 64) you were running?  Where 
you running BE and LE in same cluster?

Please be patient, however.  I don't have any ppc hardware personally, 
and getting access to non-x86 hardware may take me a few days.
