In the Solaris 9 4/04 release, on UltraSPARC II based systems, the CP Event message that accompanies some Uncorrectable Memory Error messages is not always produced. The following systems are included:
Sun EnterpriseTM 10000 system
Sun Enterprise 6500 system
Sun Enterprise 6000 system
Sun Enterprise 5500 system
Sun Enterprise 5000 system
Sun Enterprise 4500 system
Sun Enterprise 4000 system
Sun Enterprise 3500 system
Sun Enterprise 3000 system
The result is that some information needed to identify a failing CPU might not always be present.
