>From your description it's unclear whether you've built BIND with or
without sparc64_isc_disable_atomic.diff. If it was built without that
patch please give it a try. If you had applied it then this apparently
is a generic bug in BIND and unrelated to the MD atomic implementation
and I don't know how to proceed in order to get that fixed. Hopefully
Doug can help you in that case.
