iocompleterequest in filter driver

NTFSD
1

Greetings to every body,
I have developed a file system filter driver for an antivirus monitor. I
started to build it from Rajeev Nagar’s sample and I have a BSOD when its
running with Kapersky AVP.
I intercept IRP_MN_MOUNT_VOLUME calls and set a completion routine. In the
completion routine I queue a work item and return
STATUS_MORE_PROCESSING_REQUIRED. When the work item is executed I attached
to the mounted volume and complete the IRP. After some volumes are mounted I
get a BSOD (Page Fault) calling IoCompleteRequest. This doesn’t happen if
only my filter driver is loaded, with AVP Monitor comes the crash.
Am I doing something wrong?
Thanks.

Give us bugcheck analysis. There can be dozens of reasons for a bugcheck.
