WHCK test cases are failing

NTDEV

Hi ,
I am running WHCK tests on a UART driver. in I have installed the
driver and hardware in the client machine.i have got some successful results for UART compliance test for PNP related test cases.But when I am trying to
run “Reinstall With IO Before And After” ,“Concurrent Hardware and Operating System(CHAOS)”,“Fuzz Misc API test” test cases, all these test cases are failing with crash and the crash dump shows that the crash could’ve been caused by some other drivers like “fastfat.SYS” and “MSDMFilt.sys”.

How do i fix these errors which were not caused by my driver but by some other driver in the system?

Hi,

While it is possible one of the other drivers you mentioned could be the
cause of the WHCK failures, it is most likey still your driver.

Have the clients systems have been used to certifiy other Windows drivers?
Will the client systems pass the WHCK tests with a similar serial port card
(same hardware bus type and WHCK certification) installed?

That is a broad range of failures you mentioned, but the CHOAS test really
exersizes the PnP calls to change power state and surprise removal.
Possibly you could post a crash dump while your client is running the CHOAS
test.

Regards
Phil

Why don’t you post the bugcheck details ?

How could anybody help without detailed information ?

If no debugger is connected when the crash occurs, open the crashdump file in WinDbg and post the details.

Try turning the Verifier Special Pool on. Will the crash convert to a crash in your driver trivial to fix?

We’re back to try to help you debug this driver again are we, Mr. Jayanthy?

Sigh.

You already know what I think, so I’ll be quiet after this post.
