mpi350 segfault everytime!

[SirronD]

HELP!

I am trying to get the wireless mini PCI card to work in my laptop. The mini PCI card is a cisco aironet wireless mini pci card. And the driver is the cisco mpi350.

I downloaded the tar.gz from cisco, placed it into my distfile, and emerged the mpi350-driver.

That went perfectly.

But now everytime I modprobe mpi350 I get a segfault. Also, the mpi350 driver gets into an "inittializing" state and I cannot rmmod this driver, as it says Device or resource busy. Even though it "crashed" on the modprobe.

Can anyone help me?

here are the details of my system:
IBM Thinkpad T40 (intel centrino) with Cisco aironet card (I specified the cisco card because the intel does not support linux with its wireless card)

kernel: ac-sources-2.4.22_pre3-r1 (none of the 2.4.21 kernels would work. the acpi would often freeze my system on boot)

here is the oops from dmesg:

Code: Select all

I appreciate any help any of you can give me.

Thank you

Thanks to jessem77 I am now working wirelessly on my thinkpad.

First here is my current setup
Thinkpad T40 centrino using kernel: 2.4.22_pre3 (from ac-sources-2.4.22_pre3_r1).

I installed the new drivers from the Linux-ACU-Driver-v2.0.tar.gz from Cisco's website using the kpciinstall script that is inside.

I copied the ethX.cfg into /etc/eth1.cfg (my wireless mini-PCI card is eth1 on my system)

Now when I first modprobe I get immediate system shutdown (not so much as a single kernel message).

What makes it work is that I had to apply the firmware that cisco specifies. When you go to the cisco site, to download the linux driver, it also shows you a firmware upgrade to apply to the adapter. This firmware is absolutely required if you are experiencing similar problems to mine (segfaults or shutdowns). You use the ACU utility to apply the firmware to the client adapter. It only takes a few seconds to complete the process.

Once I applyed the firmware, "modprobe mpi350" inserts the driver module without any crash.

So if you have trouble with the mpi350 module in linux, try updateing the firmware with the firmware update that cisco provides along with the linux driver.

if you're looking for an alternative, the airo_mpi driver from the CVS of airo-linux on sourceforge is finally in a mostly working state. this means you can use iwconfig, and get away from the d*mn ACU utility if you so choose. See this post here and the followup here has most of the info needed to get it working. I've been using it (under 2.6.0-test1 with some patches i'm working on) for a bit now and it's great. monitor mode still doesn't really work, but otherwise things seem to finally be coming along with opensource drivers.

Any suggestions where to d/l the firmware, i can't seem to find it on the cisco site, if I go through the software selector it gives me the Linux-ACU~.. file, and another link to the firmware , except the firmware file is an .exe, so Im have a bit of a trick finding the right firmware to use.
currently I think im running 2.4.20 gentoo -r7 on my T40.
Any thoughts, help?

thx in advance

The file MPI350v50003.exe is the firmware file in a zip format. You can unzip it just with the command

Code: Select all

unzip  MPI350v50003.exe

This will give you 50C50003.IMG which is the firmware update file
