Team 386 spent way too many hours tracking this one down. When we finally isolated, we reported immediately to IFI with complete details in their forum. We had developed a workaround involving disabling high priority interrupts in the low priority interrupt exit code protecting the MOVFF instructions that were taking a hit. It conclusively proved that the issue was as documented in MicroChip's errata.
