Security and safety

"The stack alignment," Elias breathed. "You're misaligned by a word."

When the IOMMU blocks an illegal memory request, it throws a hardware interrupt. The Windows Kernel intercepts this via nt!IvtHandleInterrupt . Because an illegal memory access attempt by a core driver compromises system integrity, Windows immediately halts operations and triggers a to protect your files from corruption. Common Causes of the IvtHandleInterrupt Crash ivthandleinterrupt

The CPU looks at the Interrupt Vector Table to find the memory address associated with the specific interrupt number. Execution: The CPU jumps to the ivthandleinterrupt routine.

Toggle (Kernel DMA Protection) to Off if you need to troubleshoot hardware compatibility, though this reduces security.

If you're seeing nt!IvtHandleInterrupt in a crash dump, the root cause is rarely the function itself. The problem is that a driver or device is attempting an illegal DMA operation. Common triggers include: Because an illegal memory access attempt by a
