Goal

When there is a Peripheral Component Interconnect (PCI) bus I/O Memory Management Unit (IOMMU) fault the Solaris[TM] kernel logs a long and complex error message and may panic.

This document should explain what that message contains. The example is based on the Schizo host-to-PCI bridge computer chip that is used in most of the UltraSPARC[TM] based systems.
