What makes you think the problem could be with the spill/fill trap handlers? Looking at the architecture documents, there doesn't seem to be much difference between how sun4u and sun4v handle window spill/fill traps.
I don't suspect the spill/fill trap handling code.My suspection is the 'pcbspill' code that originally was imported from OpenBSD as part of the sun4v porting effort.
