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: 0000000000000021, the data following the pool block being freed is corrupt.  Typically this means the consumer (call stack ) has overrun the block.
Arg2: fffffa8007a9f000, The pool pointer being freed.
Arg3: 0000000000001e10, The number of bytes allocated for the pool block.
Arg4: 000dfff5000d1e06, The corrupted value found following the pool block.
