DRIVER_IRQL_NOT_LESS_OR_EQUAL

kmthien · Jul 21, 2004

Hi guys,

I am using Windows 2K Pro and a soft BIOS mainboard. I hv configured my 3Com NIC to use IRQ 7 and disable VGA card to use IRQ in the soft BIOS. But under Windows Device Manager, I still see that the NIC is using IRQ 11, which is sharing with my Creative sound blaster card, AGP card (Else Gladiac MX/MX400), and USA 2.0 + IEEE1394 card. Sometimes I got the error msg : DRIVER_IRQL_NOT_LESS_OR_EQUAL. Pls help !

regards,
kmthien

Send me the minidumps that were generated at the time of the BSOD (c:\windows\minidump) and I'll look at them and tell you (if I can) what's going on.

Typically you want to have the MB assign an IRQ to the vga card - can you tell me why you've turned this off?

Why are you configuring your NIC to any particular IRQ? Why aren't you letting the OS do that and setting it all to "auto"?

IRQ sharing is no longer an issue on a modern ACPI OS. Windows 2000 is a modern ACPI OS.

Anyway, send me those minidumps.

hi ,

Thanks for your reply. So how can I send the minidump to u ? What's ur email add?

kmthien · Jul 22, 2004

I don't quite understand what you are saying. Can you rephrase that?

Also, I suggest you allow the OS to assign all IRQs (ie don't hard-code any IRQs) and tell the motherboard to assign an IRQ for VGA.

"I'll look at them and tell you (if I can)"

If you want a 2nd opinion or get stuck, feel free to forward the dump to me dclive and I'll take a look at it.

I put my NIC in the 1st slot of PCI, which is beside AGP slot, and I got a lot of problem. Sometime I connected to the internet, the whole Windows hung, most of the time. But now I put it in slot 3 PCI, no more hang.

But I will get DRIVER_IRQL_NOT_LESS_OR_EQUAL sometimes. So I look into Device Manager and found that NIC, AGP card, sound card, USA 2.0 and IEEE1394 all sharing IRQ 11. Hence, I hardcore IRQ 7 to NIC and IRQ 5 to USA 2.0 card, which is in slot 5 PCI. pls help !

So how can I send the file to u guys?

dclive · Jul 22, 2004

On a modern ACPI-capable motherboard IRQ sharing is no longer an issue, so I don't see anything to be concerned about.

I suspect the IRQL error your getting points to something else, so please send us the minidumps you have in c:\windows\minidump. You will find my e-mail address in my sig, and Sianath has done the same in his post on the matter. Please send the file(s) via e-mail. Zip them first.

I suggest you let Windows, rather than your motherboard, handle all IRQ assignments, and set everything to AUTO in the motherboard BIOS.

Sianath · Jul 23, 2004

As a general note to anyone reading this thread:

DRIVER_IRQL_NOT_LESS_OR_EQUAL has nothing to do with IRQ assignments for hardware.

What this error means (specifically) is that a driver tried to access a memory address in pageable memory while the processor was running at an IRQL >= 2. This can't happen, because the threads that manage page faults can only run at IRQL 0, so it's impossible to resolve the fault. This is why drivers are not allowed to touch anything other than nonpaged pool when running at that IRQL.

Most drivers don't even make this mistake anymore, what happens is they try and access INVALID memory, which simulates the same stop code because we fault on access.

hi dclive, where is your sig?

I used to get the same message on an old athlon t-bird system I had about a year ago...

I would get the error when doing anything that used alot of system resources, like games, compiling, benchmarks, etc...

It did not matter what operating system that I had installed, I tried XP, 2000, and 98 (98 would only reboot and not give me the error message).

I was finally able to reproduce the problem on another computer by swapping sound cards with it. The problem turned out to be a sound blaster live 5.1 value card (It produced the problem with every driver version I could find).

I was only able to get the athlon pc working by reinstalling everything without having the sound card connected. Simply uninstalling the card and deleting the drivers did not solve the problem.

If I were you, I would swap out every component in your computer with another comp (if you have one available) one by one and see if you can reproduce the problem.

Also, dclive's sig says his e-mail is bluescreens at comcast dot net

Thanks a lot man....I will try to remove the sound blaster card. So u mean I need to format and reinstall Windows again right?

Please send us the dumps. Then we can tell you what the problem is (well, we can give it a really good shot) rather than guessing.

Don't reformat and reinstall anything. Let us look first!

Hi guys,

I hv taken out the creative soundblaster card and reformat and reinstall Windows 2K Pro. Now, The stupid Windows will restart automatically sometimes. I really don't know what's the problem now. Hope to hear from you guys soon. I hv sent the minidump files to dclive. Thank you !!

You've chosen to reformat.

After reformatting, the same issue came back. So, it's either hardware or drivers you've put onto the system.

So I need to know what drivers you've put onto the system.

dclive · Jul 25, 2004

Also, please confirm your motherboard IRQs are set to automatic, you aren't hard-coding any IRQs, and you've told the motherboard to assign the VGA card an interrupt.

Hi !
I've had this happen to me on two occasions :
1 Uncertified driver under winxp - I was using an old NIC with a driver that someone wrote and claimed to be stable.Remove NIC + the driver - problem gone.
2 Received bad motherboard (MSI K7N2 Delta-L) Replaced the motherboard - problem gone.
Is this a new build or an old system ?

kmthien · Jul 26, 2004

Hi dclive,

I have followed your instruction on upgrading nVidia driver, Onboard VIA AC97 soundcard driver, Nero driver and update Windows 2K PRo security. Seems like no more rebooting now!

Loki726:

I have removed my Soundblaster live card.

Thanks a lot guys. Hopefully no more problem !

Glad it worked!

Just a Tip please document this problem for yourself and print it next to your computer [Speaking from 7 + years troubleshooting experience , you will forget what you have done to fix the problem and go into a total state of panic when it happens again

]
An even better solution would be to slipstream the drivers in your windows 2000 so that you wont have this problem again

It was the nVidia driver. He had an old one that he was using; updating it resolved the crashes.

Gotta love those ugly bluescreen dump files.
