Bug Check 0x39: SYSTEM_EXIT_OWNED_MUTEX
The SYSTEM_EXIT_OWNED_MUTEX bug check has a value of 0x00000039. This indicates that the worker routine returned without releasing the mutex object that it owned.
Parameters
The following parameters are displayed on the blue screen.
| Parameter | Description |
|---|
| 1 | The address of the worker routine that caused the error. |
| 2 | The parameter passed to the worker routine. |
| 3 | The address of the work item. |

Cause
The worker routine returned while it still owned a mutex object. The current worker thread will proceed to run other unrelated work items, and the mutex will never be released.

A debugger is required to analyze this problem. To find the driver that caused the error, use the ln (List Nearest Symbols) debugger command:
kd> ln address
Where address is the worker routine given in Parameter 1.
