bsod every time a handle to a driver is created

im writing a driver and I have a problem

everytime I try to open a handle to my driver using CreateFile, I get bsod (Access Violation)

It's important to mention that my driver loads successfuly and I dont get any errors

does someone knows how to handle it ?

Thanks in advance!

Another possible fault source: the driver-internal function for handling IRP_MJ_CREATE is either incorrectly assigned or faulty.

But you can only guess without analyzing the dump (maybe in conjunction with the symbols database of your driver [the PDB files]).

Are you using ZwCreateFile or Createfile? You can't use CreateFile in a driver because that is a usermode function and drivers run in kernel mode. Instead call ZwCreateFile which is the kernel mode version of CreateFile.

Turn on creating Kernel Dump in Windows settings and then analyze dump in WinDbg.
