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) .
When hardware devices need processing time, they issue an interrupt. The operating system relies on core kernel routines to intercept, validate, and execute these requests securely. In modern operating systems like Windows 10 and Windows 11, functions within ntkrnlmp.exe orchestrate this process to protect system stability. However, when an invalid hardware request or rogue driver bypasses safety limits during an interrupt, IvtHandleInterrupt registers a failure, often triggering a catastrophic Blue Screen of Death (BSOD). ivthandleinterrupt
Demystifying IvtHandleInterrupt : Root Causes and Fixes for DMA Violation BSODs The kernel function is a native component of
To understand why your system crashed at nt!IvtHandleInterrupt , it helps to understand how modern operating systems handle hardware communication. 1. What is Direct Memory Access (DMA)? When hardware devices need processing time, they issue
Windows leverages the IOMMU through a feature called .
On a jailbroken iOS device or debugged Mac, you can trace all interrupts by placing a breakpoint on ivthandleinterrupt in lldb:
To resolve issues involving this function and the resulting BSOD, follow these steps: Blue Screen - DRIVER_VERIFIER_DMA_VIOLATION (e6) 21 Jan 2022 —
