CR 21694361 was fixed in Sun System Firmware 9.5.2.
This issue occurs when guest domains configured using PCIe virtual functions are rebooted. In that case, if the guest domain owning the virtual function reboots, the system might generate TTE_Invalid errors during the reboot process. These errors are harmless and can be ignored, but they will trigger system faults.
For example, type:
# fmdump -eV
2015-08-18/04:57:48 ereport.io.pciex.rc.epkt@/SYS/CMIOU0/IOH/IOS0
...
event_name = Virtual_TTE_invalid
# fmadm faulty
