Just to close this thread. I want to confess I was led astray (from the
right/straight path : ) ) by this NO_MORE_IRP_STACK_LOCATIONS message. I
was writing to an uninitialized memory which happen to belong to some
IO_STACK_LOCATION of an IRP and the system thought its because of
IoCallDriver
called without enough irp stack locations.
Thanks all who commented/tried to help.
best regards,
Hassan
