acer 4100lmi wireless kill switch problem


I have an acer 4101lmi with wireless card working under ipw2200 module. The driver loads successfully but when i type iwconfig i have a RADIO OFF message. So i have some kill switch.
Code:
 %cat /sys/bus/pci/drivers/ipw2200/0000\:06\:03.0/rf_kill 
2
It seems to be both hardware and software swtch.
If i press the switch on the front of the laptop (with a led), i get this awful error:
Code:
  atkbd.c: Unknown key pressed (translated set 2, code 0xd5 on isa0060/serio0).
  atkbd.c: Use 'setkeycodes e055 <keycode>' to make it known.
  atkbd.c: Unknown key released (translated set 2, code 0xd5 on isa0060/serio0).

 Disabling IRQ #10
 ipw2200: failed to send TX_POWER command
 ipw2200: Unable to initialize device after 5 attempts.
 ipw2200: Failed to up device
It disables the IRQ 10 and all the devices attached to it (my LAN card and sound card).
I've also tried acerhk module with the same result.

I'm beginning to panic! Anybody has any idea?

Thanks in advance.

Hi,

I have a Acer 1690 with the same intel 2200 wireless card. I used the following to enable the wireless card and the led readout
/bin/echo 0 > /sys/bus/pci/drivers/ipw2200/0000\:06\:03.0/rf_kill
/bin/echo 1 > /sys/bus/pci/drivers/ipw2200/0000\:06\:03.0/led

the led is now flashing and the front mounted kill switch now works to enable and disable wireless. Haven't fully configured the card to work yet, but see if this helps.

Although I thought I had an IRQ conflict it turned out that it was a driver issue and that the firmware wasn't being loaded at boot time.

Try this link about resolving pcmcia irq conflict.

No, it's definitely a ACPI / IRQ-Routing failure. I have to start the system with "acpi=noirq" or "pci=noapci" to get it up and running. So the system starts in PIC-Mode, and can't adress the devices behind the PCIe to PCI Bridge. The wireless-nic is a pci-device

I also think the problem is with acpi/irq routing.

I have installed the precompiled kernel from debian with nitro sources(2.6.11-nitro0e-x1-686) and it seems that acpi problem is solved. I can now boot whitout parameters like acpi=noirq.

I have some problems building ipw2200 module for this precompiled kernel (i don't have the sources for this kernel). Anybody has any idea of which is the patch or .config parameters that make acpi routing work with this "nitro kernel" ?

I had something that sounded really similar on my HP Pavilion zv6015us. I made the mistake of powering off the wireless NIC using the Windoze control panel because, at that time, I didn't have anything else wireless to connect to. I wiped Windoze when I installed FC4 test 3 and then couldn't get the wireless to come up for anything when I got a WAP for the house. When FC4 was released, I decided to do a minimal Windoze install with dual boot (that's a story in and of itself). Once I had Windoze back on the system I was able to navigate through a variety of levels in the wireless configuration to finally get the radio back on. I then installed FC4 and ndiswrapper (Broadcom NIC with no Linux driver) and it works just the way its supposed to now. GRRRR.

Nothing I could get to from Linux seemed to be capable of restoring power to the radio. I tried everything I could think of and lots of recommendations from others with both iwconfig and iwpriv. I also poked around under /sys looking for something I could prod there. There is a Sourceforge project for wireless radio power control. Do some Googling and see if your wireless NIC is supported. Otherwise, you may need Windoze on a "maintenance partition".

@DaveAtFraud:
do you experienced the same "irq 10: nobody cared!" and "Disabling IRQ #10" Problem with you HP? (It can also be an another IRQ)
I think, we get the radio powered up, but the IRQ-Routing doesn't match.


@zalis:
I've done some searches about the "nitro_sources".
The Homepage seems to be http://www.nitro-sources.org/ which redirects to http://sepi.be/nitro.php
Unfortunately without any content.
In the offical Debian-Package-Tree seems not contain the nitro-sources:
http://packages.debian.org/cgi-bin/s...ll&release=all
Can you please help out with apt-sources?

I'm using Gentoo, so i'm not so familar with debian.

No. Didn't see it. Everything I saw looked absolutely normal from the Linux side but I couldn't see any wireless traffic. My conjecture was more that somehow the radio was put into the same sort of "deep off" mode. The IRQ not getting handled is pretty odd.

You can get some info about nitro sources with gentoo at http://gentoo-wiki.com/HOWTO_nitro-sources

To get the debian precompiled kernel i think it comes from
## RAREWARES MAIN REPOSITORY
deb http://www.rarewares.org/debian/packages/unstable ./

Ok, i've tested the following kernels:

linux-2.6.11-ac1
linux-2.6.11.11
linux-2.6.12
linux-2.6.12-cko1
linux-2.6.12-love1
linux-2.6.12-nitro1
linux-2.6.12-rc6
linux-2.6.12-mm1
linux-2.6.12-mm2
linux-2.6.12-git9
linux-2.6.12-git10

Not even one does work for me

I've tried to find the 2.6.11-nitro0e-x1-686 sources, but there seems gone...
What can I do?

I've a dirty fix:
http://www.azha.de/linux/AcerTravelm...rnel.patch.bz2

Code:
<edit>
This URL is out of date now. Get the Patch under http://www.azha.de/
(see my next post)
</edit>
With this patch, the kernel can boot into the ACPI-Mode and the module ipw2200 load without complains.
The fixed DSTD-Table for the broken battery-support is also included.
Tested with kernel 2.6.12. It works for me.

Ahh! Now we're cookin'!
This works fine on my Acer Travelmate 8104 too, thanks a bunch!
Anyone knows if it would be possible to have this merged into the official kernel or mm-patch or something?

irq10 disabling and ipw2200 (to be continued)

Hi all

I wouldn't like apply the "dirty" patch since i bought an aspire 1694wlmi instead of a travelmate 4101wlmi. Time has passed but i have the same problem you met in june. I have very hard time here to configure wifi
Some of you, guys, found an other way to make ipw2200 working nicely ?

regards,

f.
