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: 0000000000000020, a pool block header size is corrupt.
Arg2: fffff8a0017a38c0, The pool entry we were looking for within the page.
Arg3: fffff8a0017a3960, The next pool entry.
Arg4: 00000000050a0106, (reserved)
