I am routinely running a Dual DPT with 38 drives on 6 busses. On 3.0-CURRENT SMP. The system did lose disk drives, either intentionally, or by accident. I cannot confirm any of Mr. Cobb's finding. I have not been funished with any data, including the panic point, which I suspect is not in the DPT code. I am still waiting for such data.
