UNEXPECTED KERNEL MODE TRAP FAQ

What is kernel trap?

The computer has two modes of operation: user mode and kernel mode. The operating system usually runs in the kernel mode, which allows the operating system to have full access to all hardware and make the machine run its any instructions.

On the contrary, user programs run in the user mode, in which programs can only perform a few instructions and don’t have direct access to the hardware.

If the software needs to access the hardware or need to call a function in the kernel, the trap instructions can make the execution flow fall from the user state into the kernel mode and transfer control to the operating system, so that the user program can call the kernel function and use the hardware via operating system.

For example, to play a movie, the video software will send a trap to access hardware like display and sound card.

What does unexpected kernel mode trap mean?

Error UNEXPECTED KERNEL MODE TRAP usually means that the Intel CPU generated a trap that the kernel failed to catch. In this part, I will introduce you three computer terminologies: interrupt, trap, and exception.

  1. Interrupt: Your PC usually works like this way: the CPU sends an instruction to the peripheral I/O device to perform the corresponding action; when the peripheral device finishes working, it will automatically send an interrupt to the CPU; when the interrupt is captured by the CPU, the CPU will then get the processing results to handle follow-up matters.
  2. Trap: It is often called software interrupt. It is a CPU instruction that makes the operating system to sends an instruction to the peripheral I/O device to perform the corresponding action. Therefore, through trap instructions, software can access hardware indirectly.
  3. Exception: It is also called automatically generated trap. The exception will be triggered when the instructions we executed encountered some abnormal situations. The unexpected kernel mode trap belongs to exceptions.
What causes unexpected kernel mode trap?

Usually, the unexpected kernel mode trap error may be caused by:

  1. 0x00000000 or Divide by Zero Error: It indicates memory corruption, other hardware problems, or software failures.
  2. 0x00000006, or Invalid Opcode: It usually indicates hardware memory corruption.
