What kind of box is this? It's calling out a whole bank of slots.

I ran into this same problem last week on a e4500. It turned out that the
Kingston RAM installed on all but one of the CPU boards was
defective. Replaced it with Sun barcode RAM and things were great. I was
able to reliably reproduce the panic running the VTS kmem test.

If you have a mix of manufacturers for your DIMMS then try making
everything from the same maker, or better yet, try all Sun.
