load kernel driver as system fail

NTDEV
1

Hi,

I wrote a kernel driver and try to load it at system instead of boot time
and it works.
However when I try to run it together with drivers (file filter driver and
disk filter driver, both starting on boot), my driver will fail to run.
Why is that so?
However if I start it at Boot, it will run too.

What could be the possible cause?

Thank You!

cheers,
vincent

Are you receiving any kind of error statuses or messages? If so what are
they?

stopped.

Depending on the type of kernel driver involved and where it resides within
a driver stack Windows may not be able to restart the devices. For example
if you install an upper filter HBA bus driver on a host where the boot disk
is attached to an HBA adapter you must reboot the host because restarting
the boot disk’s driver stack cannot happen.

You might want to check the setupapi.log file located in %SystemRoot%. It
may give you some useful information.

You didn’t specifically say what your kernel driver does. I assume its a
filter driver of some kind?
