Hi,
I have a problem with function IoInitializeDpc(..) in the DriveryEntry.
I have checked it on two computers, and on one it takes system down on the
othere it works fine (more or less I'm not sure, but it should).
Can someone explain this to me. What could be wrong?
Regards,
Nenad

You really haven't supplied enough detail for anyone to help you. Basically
you've said little more than "my driver is broken, what could be wrong?"
However, I'll take a wild ass guess:
1) your call to IoInitializeDpcRequest in driver entry does not anticipate
that your dpc routine could actually run anytime after you issue the call,
including before you return from IoInitializeDpcRequest.
2) you have not supplied the correct parameters to IoInitializeDpcRequest,
or the parameters you have supplied are not in the appropriate state.
You should try putting a break point in your dpc routine and seeing if you
get there. You should set up crash dumps on your test system and try
analyzing the crash.
