The DRIVER_PORTION_MUST_BE_NONPAGED bug check has a value of 0x000000D3. This indicates that the system attempted to access pageable memory at a process IRQL that was too high.
The following parameters are displayed on the blue screen.
| Parameter | Description |
|---|---|
| 1 | Memory referenced |
| 2 | IRQL at time of reference |
| 3 | 0: Read 1: Write |
| 4 | Address that referenced memory |
If the driver responsible for the error can be identified, its name is printed on the blue screen and stored in memory at the location (PUNICODE_STRING) KiBugCheckDriver.
This bug check is usually caused by drivers that have incorrectly marked their own code or data as pageable.
To begin debugging, use a kernel debugger to get a stack trace.
