Resolution for UP_DRIVER_ON_MP_SYSTEM
Diagnostic focus
Parameter 1 is the base address of the incompatible driver image. Resolve that address to the loaded module, record its file version and build origin, and verify that the installed binary was built for multiprocessor Windows. The corrective action is to replace or rebuild that specific driver with an MP-safe version; disabling processors merely hides the compatibility defect and is not a valid driver fix.
