BAD_POOL_HEADER (19)
The pool is already corrupt at the time of the current request.
This may or may not be due to the caller.
The internal pool links must be walked to figure out a possible cause of
the problem, and then special pool applied to the suspect tags or the driver
verifier to a suspect driver.
Arguments:
Arg1: 0000000000000003, the pool freelist is corrupt.
Arg2: fffffa8003964580, the pool entry being checked.
Arg3: 0001cb0201270001, the read back flink freelist value (should be the same as 2).
Arg4: fffffa8003964580, the read back blink freelist value (should be the same as 2).

Debugging Details:
------------------

So, now it is better to enable Driver Verifier to monitor the drivers.

Driver Verifier - Enable and Disable

Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

Let us know the results, with the subsequent crash dumps, if any.
