Hi Gurus
I have a driver which I am trying to install. But installation of the
driver is breaking into the debugger and giving a page fault error
page fault(0Eh) fault 0000
Well, the culprit seems to be the KegetCurrentIrql(). On removing the
instances of this function from my code, there is no problem of
installation. How can installation cause a page fault error?? Is there
some other problem with my driver?? wat could that be? Am I using the
Kegetcurrentirql() correctly??
ASSERT(Kegetcurrentirql()<=0x02); //checking for dispatch level or less.
Thanks in advance

I had one instance like this if it matches yours.
Are you displaying any unicode string some ware like-
DbgPrint(“\nfullFileNameWrt:%wZ!”,&fullFileNameWrt);
Using %wZ at IRQL > 0 gives a page fault(0Eh)
-a

I get the problem only while asserting the IRQL
And i have the assert on passive level

Could you supply the !analyze -v info, so that we can see what’s on the
stack. If you’re struggling with a debug issue like this, there’s no such
thing as “too much information”, whilst it’s very easy to have “not enough
information”.
Obviously, you can replace any function/module name that would be
indicating which device/company is involved with “mydriver” and
“myfunction”, so that your “anonymity” is ensured.

I have seen instances where the linker forgot to generate an import
table entry for KeGetCurrentIrql. This meant that when KeGetCurrentIrql
was called no dynamic link fixups had been done and the system branched
to 0.
Aso others have said. Get a backtrace from !analyze -v and we will be
able to give much more informed help.

Eh? I’ve never seen that.

The only time I have ever seen something like this was with a stupid hack to
build a driver from Visual Studio ignoring the build process.

Nope. All done using DDK build environment using the DriverWorks C++
libraries. This was an NDIS miniport spread over multiple directories
with the final driver being build from component libraries. Never
worried about it too much as I managed to find a workaround.

Ok, so still non-standard (DriverWorks C++ is far from standard).

C++ isn’t standard? Maybe it isn’t the norm for drivers, but it certainly
isn’t a hack, nor would I reach out to call it non-standard. DriverWorks
doesn’t do anything outside of the language that I am aware of. So, either
the linker works or it does not. I have never seen this problem though, and
I have used DriverWorks/DriverNetworks a bit.
