PP0_INITIALIZATION_FAILED

PP0_INITIALIZATION_FAILED is specifically the Phase 0 initialization failure of the kernel-mode Plug and Play manager. Microsoft publishes no bug-check parameters for this code, so there is no status argument to decode from the four stop parameters.

Why the phase matters

This is not the same code as PP1_INITIALIZATION_FAILED. The PP0 reference identifies the earlier PnP-manager phase, while PP1 names Phase 1. Keep the distinction when comparing boot failures: a workaround or driver hypothesis derived from a PP1 dump should not be transferred to PP0 solely because both names mention PnP initialization.

Debugging focus

Preserve a kernel dump and use !analyze -v to identify the boot-time call stack.
Compare recent boot-critical driver, firmware, and device-enumeration changes with the first failing build.
Because the code has no public parameters, rely on stack and loaded-module evidence rather than assigning meaning to arguments 1-4.
