DRIVER_VERIFIER_DMA_VIOLATION (0x000000E6)

What is DRIVER-VERIFIER-DMA-VIOLATION?

DRIVER_VERIFIER_DMA_VIOLATION (0x000000E6) is a high-severity system driver issue. Stop code 0xE6 indicates a driver performed an illegal DMA (Direct Memory Access) operation. DMA allows hardware to access system memory directly without CPU involvement for performance. When Driver Verifier is enabled and catches a driver performing DMA to unmapped or invalid memory regions, it immediately crashes the system to prevent silent memory corruption. Follow the steps below to fix it.

Common Causes

• Buggy driver performing DMA to invalid address
• Driver not properly mapping DMA buffers
• Hardware with incorrect DMA capabilities

Step-by-Step Fix Guide

• 1
  Identify faulting driver via Driver Verifier log

  This BSOD only occurs when Driver Verifier is active — disable it with 'verifier /reset' to restore normal operation while finding the root cause.

• 2
  Update the hardware driver to latest version

  The specific violation type in the bugcheck parameters (param1) identifies whether it's a map failure, unmap failure, or buffer overflow.

• 3
  Contact hardware manufacturer if driver bug confirmed

  "Contact hardware manufacturer if driver bug confirmed" is worth trying when buggy driver performing DMA to invalid address turns out to be the culprit.
