Are you using HalAssignSlotResources ? If so have you tried passing
DeviceObject in HalAssignSlotResources in your NT4.0 style driver ? On win2K
DeviceObject must be passed. On Nt4.0 it was optional.
Hope this helps.

You aren’t the first one to hit this, but I don’t remember the solution.
I believe the issue is related to how HALMPS uses the APIC.
I’d expect the same symptoms if you use HalMps with one CPU.
