We did play with some of the slot settings in the bios to no avail.
We're in mid-test of the slot 2 riser solution (which has worked fine
over the whole weekend at a load average between 3 and 6 and with the
disk and network being heavily banged on all the while, so it looks like
it works).  As soon as it finishes (or I feel like grabbing another of
the idle chassis to test with and open it up) I'll give this a more
focused try.

It does have the feel of a latency issue, but why slot 1.  Why slot 1
when the system is (otherwise) entirely empty?  I'm not asking you,
understand, just looking to heaven for Enlightenment...
