Help me please: ipw2200: Error allocating IRQ 18

evolutionspeak · 10-01-2005, 06:34 PM

I can't seem to get my wireless to work on my centrino notebook. This looks like an IRQ conflict to me but I have no idea how to see what is on what IRQ or how to resolve it or how to do anything at all.

Please help me.

You have not provided much information. What Linux kernel is your Linux distribution using? In a terminal, type: cat /proc/version

What are you seeing that is telling you it's an IRQ issue? Are you able to tell which one, like 11 or 5?

youngstorm · 10-01-2005, 09:32 PM

Hi,
Does linux see it at all?

evolutionspeak · 10-02-2005, 07:30 PM

Sorry about the lack of info.
This is what cat /proc/version gave me:
Linux version 2.6.11-1.1369_FC4 (bhcompile@decompose.build.redhat.com) (gcc version 4.0.0 20050525 (Red Hat 4.0.0-9)) #1 Thu Jun 2 22:55:56 EDT 2005

The message I got I read from dmesg:
ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.0.0
ipw2200: Copyright(c) 2003-2004 Intel Corporation
ACPI: PCI Interrupt 0000:06:06.0[A] -> GSI 18 (level, low) -> IRQ 18
ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection
ipw2200: Error allocating IRQ 18
ipw2200: probe of 0000:06:06.0 failed with error -22
snd_intel8x0: Unknown parameter `'

The OS seems to see the card. When I go to the Network GUI thing under the desktop menu it shows up as eth1 but I can't activate it. It says the device is not present. I have tried toggling the wireless button on my laptop but it doesn't seem to help.

IRQ 18? Unless hardware has advanced further than I have thought -- there IS a move coming up to a new standard -- there ain't no IRQ 18; instead, like most everything else where hardware is concerned, we're dealing with Hex numbers here and the highest assignment, at least in the past, has been to IRQ 15 (the first interrupt number is to IRQ zero). Unless this industry standard has changed, then the problem here is that the user is attempting to assign an interrupt channel that does not exist.

rk_carol · 10-03-2005, 10:56 AM

1. Open a console session or an xterm window if you are using a GUI
2. cat /proc/interrupts
The above command will show you all the IRQ lines open as well as the various devices ( both shared
as well as non-shared) that use the IRQ lines.
3. You can see whether another device is using IRQ18.

My best guess is that your sound card is using IRQ18 and that it has acquired the IRQ as non-shared.

You can rmmod your sound card drivers ( either by commenting the relevant entries in /etc/modules.conf) and try rebooting.

one option that you may look into:

check your bios and set PLUG AND PLAY OS to NO ... this forces your bios to handle the assigning of IRQ's.

this may fix your problem, as well.

evolutionspeak · 10-03-2005, 04:28 PM

I did a cat /proc/interrupts and this is what it returned:

Code:

           CPU0       
  0:     160063          XT-PIC  timer
  1:        285          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  8:          1          XT-PIC  rtc
  9:         35          XT-PIC  acpi
 12:       8205          XT-PIC  i8042
 14:       7406          XT-PIC  ide0
NMI:          0 
ERR:          0

So it appears that IRQ 18 is free. Unfortunately my BIOS is really lame (fsck you hp) and doesn't even give me that plug and play OS option. Here is a copy of my dmesg. As you can see I have a whole bunch of IRQ related errors. Thanks a lot for your help guys it is greatly appreciated.

Edit your kernel bootup command line by adding the following :

acpi=noirq

If you are using lilo, you can use

append="acpi=noirq"

If you are using grub, select the image you want to boot, using 'e' and edit the line, adding the above and then boot.

I strongly suspect that ACPI is cludging the IRQ lines. From your boot message, I suspect that other devices too may not be working such as USB,
soundcard, Bluetooth etc. not just your wireless lan.

Try the above...

that worked perfectly, thanks

now I just have to get WPA working

Staring at my unbootable laptop, contemplating hari-kari, I stumbled across this thread. Eureka! Boot sequence stops on an acpi error - why not turn it off? Doing as you suggest made the box bootable again. I'm writing this on it. THANX!

Another problem I had was that it couldnt use any IRQs and /var/log/messages said some blah blah and "try pci=biosirq". I tried that and it worked fine.
You can also try pci=userpirqmask.

Ok after fighting this off and on for a couple of months now I added

Quote:

acpi=noirq

to my menu.lst and everything started working normally again. FWIW I was using SuSEPro 9.3 and my ipw2200 nic would work, powermanagement would work but not usb. I went to SuSE 10 and usb and powermanagement worked but the nic was flaky. I tried adding

Code:

irqpoll

to grub which allowed the nic to work but screwed up power management. (I use power management frequently on my notebook along with a palm usb pda).

But now with the

Code:

acpi=noirq

code everything is working beautifullly. Thanks!

Apparently a lot of people are happy with the small piece of advice I sent !

Always ready to help...

Thanks.
