Do you have more than one CPU?  And if so, does your dump ELF notes
section have CORE notes for all CPUs (readelf --notes should give be
able to give you this info)?  I notice that the note to CPU mapping is
incorrect for mips if some CPU (other than the last one) didn't save its
registers.  I've just sent a patch to the list to fix that and some
other problems with the dump register handling, could you please try
that out and see if it gives you a backtrace?
