When you see the violation message, the PC watchdog i.e. the bug checker is overwhelmed. The reason for this might be the longtime running of the DPC or your system being stuck at interrupt request level (IRQL) of DISPATCH_LEVEL or above.
Now, you might want to know that when you will see this type of error. Then, let us inform you that if your device driver is installed wrongly or is outdated then there are chances of seeing this type of error.
