STATUS_ACPI_REG_HANDLER_FAILED
STATUS_ACPI_REG_HANDLER_FAILED means that an attempt to register an ACPI event handler failed. The failure occurs at the registration stage; it does not state that a successfully registered handler later received a malformed event or that the device’s hardware action itself failed.
Start with the event category, target, registration owner and lifecycle state. A duplicate registration can yield STATUS_ACPI_HANDLER_COLLISION; other registration failures can involve an invalid event type, unsupported target or unavailable prerequisite state.
Registration of an ACPI event handler failed
- Record the event type, identifier, handler owner and exact registration API or initialization phase.
- Check whether the target is represented in the current ACPI table set and whether its event block or device object is present.
- Trace matching unregister paths so stale registrations are not confused with a fresh registration failure.
