I was just about to start swapping motherboards when I received the
following mail from Ray Trzaska (rtrzaska@uk.mdis.com), which solved the
problem. Thanks Ray, and also to those who wrote with other suggestions.

--original message--
this is a good one, and had sun support claiming that they had never
seen this before, and then that something similar was seen in japan...
anyway it is a known problem with a simple fix , check the
upa-noprobe-list from OK prompt or eeprom command -

SRDB ID: 18357

SYNOPSIS: e450 only shows 3 out of 4 cpu's under psrinfo or prtdiag

DETAIL DESCRIPTION:

e450 with 4 cpu's installed..
but psrinfo and/or prtdiag only show 3 of them

SOLUTION SUMMARY:

set the upa-noprobe-list to 0
at the OK prompt....

OK setenv upa-noprobe-list 0
OK reset-all

That's it, all 4 cpu's should now show up with psrinfo or prtdiag.

regards
ray
