DRIVER_VERIFIER_DMA_VIOLATION

DRIVER_VERIFIER_DMA_VIOLATION meaning

DRIVER_VERIFIER_DMA_VIOLATION is bug check 0x000000E6. DMA Verification detected invalid direct-memory-access behavior. Parameter 1 identifies the specific violation; other parameters describe the adapter, map registers, buffer, or transaction involved.

How to analyze the result

Decode Parameter 1, identify the DMA adapter and driver, inspect map-register and common-buffer lifetime, direction, alignment, and whether IOMMU or DMA remapping reported a fault. Preserve device and firmware identity.

Preserve the complete dump, all four parameters, Windows build, loaded modules, and the event timeline before changing drivers or firmware while investigating this result.
Run !analyze -v and follow the parameter-specific objects and the stack associated with this result rather than relying only on the symbolic name or a single probable-cause line.
Compare multiple dumps when available; a stable instruction or object path associated with this result is stronger evidence than a module that appears only after earlier corruption.

Recovery boundary

Repair the driver DMA contract or device firmware. Disabling DMA verification can confirm the trigger but must not be treated as a fix for writes outside the authorized mapping.
