A driver didn't fill out a dispatch routine for a major IRP function code.
Although the dump hasn't saved much, the device associated with the IRP isn't available, nor is the lock waiting on the IRP.
We'll need either a new dump, or a larger one.
The larger one is located in C:\Windows\memory.dmp
Upload it to a 3rd party file sharing site.
