Code:
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, [B][COLOR=Red]and then special pool applied to the suspect tags or the driver
verifier to a suspect driver[/COLOR][/B].
In such a situation, 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.
And you may disable driver verifier, too.
