DRIVER_VERIFIER_IOMANAGER_VIOLATION
DRIVER_VERIFIER_IOMANAGER_VIOLATION meaning
DRIVER_VERIFIER_IOMANAGER_VIOLATION is bug check 0x000000C9. I/O Verification detected a fatal misuse of IRPs, device objects, completion, cancellation, or other I/O manager contracts. Parameter 1 selects the exact rule.
How to analyze the result
Use Parameter 1 and the rule-specific parameters to locate the driver, IRP, object, or dispatch routine. Check ownership, stack locations, completion calls, pending status, cancellation synchronization, and object lifetime.
Recovery boundary
Correct the I/O path in the responsible driver. Suppressing verifier only removes detection; it does not make an invalid IRP or object transition safe.
