Stratus Technologies of Maynard Massachusetts (www.stratus.com) manufactures fault tolerant servers. The current Stratus products use Nehalem CPUs and the servers are supported with Red Hat Enterprise Linux, VMware ESX, Windows and VOS. I have no access to servers with OHCI. In my testing, although both EHCI and UHCI are present in the ICH10, the problem always was associated with the UHCI controller. Robert N.
