Treat GC buffer busy as normal buffer busy wait event. If you have my
OWI/RAC book there are some scripts the book and you can find the system
calls causing the buffer busy wait .

Or  look at the segment statistics and see the segments/object responsible
for those waits. It would be pretty simple once you get the culprit objects.
