When you are using some third-party SCSI filter drivers, you may receive error messages that refer to either the SCSI class drivers or the third-party filter driver. The exact stop code will vary, with "STOP 0xA" and "STOP 0x1E" being the most common.
The Windows NT SCSI Class driver does not properly handle a notification event when sending SCSI_IOCTL_GET_INQUIRY_DATA, so an underlying filter driver that handles the request asynchronously may cause an error message on a blue screen (STOP screen).
This happens because the event being used to signal that the asynchronous request has been fulfilled is not reset properly on a retry of the request, causing the next I/O packet to be set before the request is finished.
