PCI Driver on W2K. HELP???

NTDEV
1

Hi All,
I am working on a PCI driver and facing a very strange problem.
Environment is :
Win2k Server with SP2, SRP1.
To explain the problem i’ll have to give the scenerio.

  1. Add one PCI device on the system and boot the system.
  2. Now down the system and add another PCI device.
  3. At boot up time driver added both the device but after bootup it shows
    the New PCI device found box and start installing it again and thats it…
    Screen of death…

Any help…
Thanks in advance.

Dave,

So you have a bug in your driver. You need to debug it. We could all
guess at the many ways that you could have screwed up managing multiple
devices in your driver, but it would be a lot easier if you either:
a) debugged your problem or,
b) provided at least some information to us about the exact bugcheck and
system state. Stack frame? Bugcheck code and parameters?

Here is a hint: check your remove device processing path.

Here is another hint: use driver verifier.

i am debugging the driver but still didn’t able to find the cause of problem
One strange behaviour i saw is:
I reinstall the win2K and then worked with the two PCI devices. Hey!!! it work fine.
Then i uninstall both the PCI devices through device manager and restart the machine first with only one PCI device, it worked, then with two PCI devices, it crashed.
Please reply if something click your mind.

“Kernel symbols are WRONG. Please fix symbols to do bugcheck analysis”

It is really hard to get a symbolic debugger to work if you don’t
configure it to use the correct symbols.

Bug Check 0xD1: DRIVER_IRQL_NOT_LESS_OR_EQUAL

The DRIVER_IRQL_NOT_LESS_OR_EQUAL bug check has value 0x000000D1. This
signifies that the system attempted to access pageable memory at a
process IRQL that was too high.

Parameters
The following parameters are displayed on the blue screen.

Parameter Description
1 Memory referenced 0000000c
2 IRQL at time of reference 00000008
3 0: Read 00000000
1: Write
4 Address that referenced memory f06c9926

In your ISR, or a function called by your ISR, a null pointer was
dereferenced at offset 0x0c with a read operation. This caused a page
fault in the ‘zero-page’ guard page. The function is near location
f06c9926.

You MUST install the correct symbols for windbg and then either point
windbg at the kernel dump, or re-run the test failure case. Then once
you are at the crash, do exactly as the instructions say to do: run
‘analyze -v’.

Thanks a lot Mark

You were right, there was a bug in the remove device path, i.e. there
was no disconnection for the interrupt connected at device addition
time.

i have solved the issue and credit goes to you.

thanks again…

David
