The system will panic with either of the following panic strings:

"SUNW-MSG-ID: SUNOS-8000-0G" will be seen in /var/adm/messages and 'fmadm faulty', eg:

genunix: [ID 843051 kern.info] NOTICE: SUNW-MSG-ID: SUNOS-8000-0G, TYPE: Error, VER: 1, SEVERITY: Major
unix: [ID 836849 kern.notice]
^Mpanic[cpu9]/thread=fffffe8000a65c60:
genunix: [ID 647700 kern.notice] pcieb-4: PCI(-X) Express Fatal Error. (0x101)
