Can we expect a thread for every PnP IRP minor function code?!

The reason is stated right here “Caller has completed successful IRP_MJ_PNP instead of passing it down (Irp = 89942F00 ).” You completed the IRP when you should have only passed it down. You’ve got the address of the IRP, and an !analyze -v may show you the failing function.

I posted the explanation last Wednesday, the first time you sent this.
Are you saying you did not understand the explanation?

OK, I’ll try to restate it. Plug and play requests (IRP_MJ_PNP) must be
received by ALL of the drivers in a driver stack. Every driver must be
allowed to handle them. That means that a driver is not allowed to
complete such an IRP, because that stops its progress. Instead, you
must hand it to the next driver in the stack. Sometimes you process it
first and then hand it down, and sometimes you hand it down and process
it on the way back. The documentation describes which is which.
The driver verifier makes sure that you follow this rule, and this blue
screen happened because your driver did NOT follow the rule. You got an
IRP_MN_QUERY_STOP_DEVICE request, where P&P is asking if you are able to
be stopped, and your driver completed the request without handing it to
the next driver in the stack.
