Microsoft’s technical cause notes add: A driver that is compiled to work only on uniprocessor machines has been loaded, but the Microsoft Windows operating system is running on a multiprocessor system with more than one active processor.

Safe next steps

  1. For 0x00000092 (UP_DRIVER_ON_MP_SYSTEM), record the stop code, four parameters if available, and the driver file shown on screen or in the dump.
  2. If Windows starts, compare recently changed drivers with the exact PC or device maker’s support page. Use Safe Mode only if normal startup fails.
  3. A named module may be where Windows stopped, not the proven root cause. Avoid broad driver removal.

After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
