Encountering a crash with IvtHandleInterrupt is rarely a problem with the kernel itself. It is almost always a symptom of a problem elsewhere, typically related to drivers or hardware configuration.
: The most common cause is the Verifier tool itself being active. Open Command Prompt as Administrator. Type verifier /reset and press Enter. Restart your PC.
A peripheral raises an interrupt request (IRQ) line to the interrupt controller (e.g., NVIC on ARM Cortex-M, GIC on ARM Cortex-A, or PIC on x86).
: Sometimes the tool itself is left running after troubleshooting, causing BSODs for minor issues that wouldn't otherwise crash the system. Microsoft Community Troubleshooting Steps ivthandleinterrupt

The kernel function is a native component of the Windows kernel core system architecture ( ntkrnlmp.exe ) responsible for handling hardware interrupts generated by the IOMMU (Input-Output Memory Management Unit) when a Direct Memory Access (DMA) violation occurs. When a peripheral device tries to read or write to an unauthorized system memory address, the IOMMU blocks the request, triggers an interrupt, and passes execution to nt!IvtHandleInterrupt . This sequence forces Windows to immediately halt operations and display a Blue Screen of Death (BSOD) featuring the stop code DRIVER_VERIFIER_DMA_VIOLATION (0xE6) . Encountering a crash with IvtHandleInterrupt is rarely a
: The Input-Output Memory Management Unit (IOMMU) may incorrectly flag legitimate operations if the BIOS/UEFI is outdated. Active Driver Verifier
is a critical internal Windows kernel module function that handles Interrupt Vector Table (IVT) routing, manages Direct Memory Access (DMA) transactions, and bridges communication between hardware devices and the CPU via the Input-Output Memory Management Unit (IOMMU).
He wasn't looking at the robot's arm; he was looking at its brain, specifically the Interrupt Vector Table (IVT). This was the phone directory of the processor. When the robot’s optical sensor saw an obstacle, it triggered a hardware interrupt. The CPU stopped what it was doing, looked at the IVT, found the address for the "Emergency Stop" routine, and executed it. Open Command Prompt as Administrator
is a critical internal function within the [Windows Kernel (ntkrnlmp.exe)](microsoft.com that manages hardware events and enforces memory safety under the IOMMU (Input-Output Memory Management Unit) framework. When low-level drivers or system modules attempt unsafe Direct Memory Access (DMA) operations, this function triggers the dreaded Blue Screen of Death (BSOD) stop code: DRIVER_VERIFIER_DMA_VIOLATION (0xE6) .
ivthandleinterrupt is the dispatcher. It is the code responsible for saving the current state of the processor, executing the necessary logic for the specific event, and then restoring the processor so it can go back to its original task without a hitch. How the Process Works
: Most frequently graphics, network (wireless adapters), or storage drivers. Kernel DMA Protection
The name of the stop code can be highly misleading. Many users encounter this error even when they have . The primary reasons IvtHandleInterrupt gets called include:
In modern systems utilizing Kernel DMA Protection , hardware sub-systems are isolated by the IOMMU. The IOMMU functions like a standard virtual memory manager, but for peripherals. It ensures that a device can only read or write to physical memory regions explicitly allocated to it.
