I’ve gotten a dump file that shows a BAD_POOL_HEADER bugcheck in a Kmdf
worker thread. So far it’s got me stumped, if it’s my bug.
The crash occurs in an internal Kmdf worker thread, doing some inscrutable
C++ stuff. While the bugcheck indicates a problem with the size field, that
does not appear to be the case. The pool being freed is already free (and
previously owned by Ntfs).
The current state of things is that a general object with several offspring
objects is being deleted. One of the offspring objects is a manual queue.
In response to an ioctl, an attempt was just made to forward a request to
the manual queue. That failed, and the request was completed with
STATUS_DEVICE_BUSY.
I have appended relevant windbg output below.
Any ideas?
Thanks,
- Dan.

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: 00000020, a pool block header size is corrupt.
Arg2: 89082d50, The pool entry we were looking for within the page.
Arg3: 89083990, The next pool entry.
Arg4: 89885b58, (reserved)
