It is an Adaptec 7902 that is on the Motherboard.

I know termination is important. The cable has an active terminator, and
the card is also terminated.

I will try that. I already tried on a similar whim turning off the
hyperthreading support in the Xeon's.

I ran full diagnostics on the motherboard. It passes all tests.
