DRIVER_PNP_WATCHDOG
The DRIVER_PNP_WATCHDOG bug check has a value of 0x000001D5. This indicates that a driver has failed to complete a PnP operation within a specific time.
DRIVER_PNP_WATCHDOG Parameters
| Parameter | Description |
|---|---|
| 1 | First few character of the service associated with the devnode. |
| 2 | Pointer to the nt!TRIAGE_PNP_WATCHDOG on Win10 RS4 and higher. |
| 3 | Thread responsible for the PnP Watchdog. |
| 4 | Milliseconds elapsed since the watchdog was armed. |
Cause and diagnosis
A Plug and Play operation exceeded the watchdog interval. Parameter 1 carries the beginning of the service name associated with the devnode, Parameter 2 points to TRIAGE_PNP_WATCHDOG on supported Windows 10 builds and later, Parameter 3 identifies the watchdog thread, and Parameter 4 records the elapsed time.
Run !analyze -v, inspect the watchdog thread from Parameter 3, and follow the pending PnP request into the device stack. Preserve the devnode/service identity and the blocked stack so the driver that is waiting can be distinguished from a lower device or filter that never completed the operation.
