ipw3945 doesn't work after gutsy update (2.6.22-10), SRU TEST CASE

i had a similar problem. the problem was that grub was booting a 2.6.22-10-i386 kernel instead of 2.6.22-10-generic. selecting the generic kernel on startup fixed the problem for me...

on HP DV 2220tx....same thing happened after the update....

along with WIFI i even lost Sound Card.

Today, after a 3th reboot, everything works!!! I really sorry, but I don't know what fix it, because I didn't apply any update.
My grub is fine, boot up the same kernel as before.

The only difference is that i have installed the restricted-manager package and installed alsa-drivers (from source) with a patch for my sound card.
It might be a hardware issue after all.

For me, this strange bug can be closed,
but since others are having this issue, we may trace this.
Any idea how?

@Re Alvarez : have you checked for the generic kernel as mentioned above? for the sound problem see bug #134146 at https://bugs.launchpad.net/bugs/134146

i am still facing this issue....i have booting with generic kernel and not i386....i already rebooted about 6 times...with no results...

@Winkler....
Was your sound not working too? How did you install restricted-manager package?? can you give me the details so i can fix my laptop too...

thanks in advance,

@Re Alvarez:
To fix the sound I used this tip: http://ubuntuforums.org/showpost.php?p=2997056&postcount=15

and I have installed the restricted-manager using apt-get. But I have the feeling that this bug is not related to this package.

I hope it will help. If You need some thing else, let me know.

Same issue on Dell XPS M1210, along with no sound.

Since there are no news, and I have my wireless working (I can't backtrace), I will change the status of this bug. If someone disagree with me, feel free to change.

I'm noticing something similar, but it's only happening with the rt (realtime) kernel. I have these packages installed:

ii linux-image-2.6.22-11-generic 2.6.22-11.33 Linux kernel image for version 2.6.22 on x86
ii linux-image-2.6.22-11-rt 2.6.22-11.33 Linux kernel image for version 2.6.22 on RT
ii linux-restricted-modules-2.6.22-11-generic 2.6.22.3-11.4 Non-free Linux 2.6.22 modules on x86/x86_64
ii linux-restricted-modules-2.6.22-11-rt 2.6.22.3-11.4 Non-free Linux 2.6.22 modules on Realtime ke

I don't have any other 2.6.22 kernels or modules installed.

When I try to load the ipw3945 module after booting the -rt kernel, I get 'invalid module format'. Rebooting with the -generic kernel, everything works perfectly.

Maybe it's not related at all, but seems similar...

Booting with 2.6.22-12-generic I have no problems. With 2.6.22-13-generic the ipw3945 driver just doesn't load. locate tells me there are different files installed for these two kernel builds. It seems like the ipw3945.ko is missing from the 2.6.22-13 build, together with the firmware ipw3945.ucode.

Do you have linux-restricted-modules for 2.6.22.13 installed?

I ran into the same issue on my ThinkPad X60. Both -386 and -generic 2.6.22.12 work, -386 2.6.22.13 doesn’t. All of the relevant linux-restricted-modules{,-386,-generic} installed in 2.6.22.13 versions.

And now I just checked that -generic 2.6.22.13 works as well, to this issue seems to be specific to -386 in my case (in much the same way it’s specific to -rt for Jon-o Addleman).

FWIW, this is still the case for me with 2.6.22.14 – -generic works, -386 doesn’t.

This is a critical bug, I won't be able to use wireless ipw3945 with gutsy. The latest update to 2.6.22-14 doesn't bring the ipw3945.ko module.

Seems the package linux-ubuntu-modules-2.6.22-14-generic was not installed when upgrading. I installed it manually, to see if that fixes the problem.

did you have linux-image-generic installed?

This gets installed with the gutsy cds - is this an upgrade bug only?

Might be an installer bug

Installed packages

All my problems disappeared after running "sudo depmod -a"

ipw3945 requires linux-restricted-modules-2.6.22 as well as linux-ubuntu-modules-2.6.22 to be installed.

That's right but the problem seems to be that depmod wasn't run at install time.

For me, everything is working, for a long time.
But I'm chasing the a alsa bug, so I have done lots of depmod.

If anyone need a specific info, please ask.

Actually, it runs depmod but with an incorrect option '-A'. I discovered this little gem while doing the backports module.

Gutsy lum commit 1dd3609f422ff59911ece1c6ae2eefacc13cb3af

Both linux-image-2.6.22-14-386 2.6.22-14.46 and linux-image-2.6.22-14-generic 2.6.22-14.46 work for me – thanks for fixing this!

The secret it installing linux-ubuntu-modules-2.6.22-14-386.

After installing Gutsy, things worked fine with the 2.6.22-14-generic kernel, but in the -386 kernal, ipw3945 was enabled but not "in use." Loading the above package solved the problem.

linux-ubuntu-modules-2.6.22_2.6.22-14.38 is currently in the unapproved queue.

This patch updates lum postinst and postrm hooks so that depmod detects _all_ modules correctly.

Accepted into gutsy-proposed, please test and give feedback here.

TEST CASE: versions of postinst/postrm hooks prior to lum 14.38 called depmod with the '-A' option which only looks at modules newer then modules.dep. If you have installed or removed packages in just the right order you can create a modules.dep that does not correctly describe the module relationships, especially in the case when there are multiple modules that support the same hardware.

There isn't really a good test case for lum, I found this problem with linux-backports-modules which is far more likely to get removed and installed (and exhibit the problem). However, I wanted to change the use of depmod in Gutsy lum now so that I don't forget to add it to the Hardy version of lum.

marking as invalid for > gutsy, source package in question does not exist there. please open a separate linux-ubuntu-modules-2.6.24 task if needed.
