Bug Description

On my XPS M1330, since my last update to Intrepid, I have many random freeze.
My caps lock and num lock blinks together and I always must restart my computer (Can't access to new term ...).

This problem is present on my last kernel (2.6.27-7) and my 2 old kernels (2.6.24-20 and 2.6.24-21). I hadn't this problem before my update with these 2 kernels.

I suppose a problem with my network interfaces but I'm not sure ...

This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage.
I have classified this bug as a bug in kernel.

This bug seem to be a WiFi connection problem.
I have many troubles with it at work ... but not at home (very strange).
When i remove my Wireless connection at work : no freeze.

So this is my WiFi hardware :

Hi Squaredge,

Since you mentioned this appears to be related to wireless, you might want to try installing the linux-backports-modules package. It recently pulled in an updated version of the compat-wireless stack:

https://edge.launchpad.net/ubuntu/+source/linux-backports-modules-2.6.27

linux-backports-modules-2.6.27 (2.6.27-7.3) intrepid; urgency=low

  [Tim Gardner]

  * Added iwlwifi firmware
  * Added the upstream compat-wireless-2.6 tree.
  * Updated compat-wireless to wireless-testing tag master-2008-10-14
  * Set CONFIG_WIRELESS_OLD_REGULATORY=y by default.

It may help here. Let us know. Thanks.

Changed in linux:
status: New → Incomplete

Thanks for your post Leann !

After many search on this tracker, I definitively thinks this problem is due to my Wireless card.
Another ticket treat this bug and symptom are exactly the same with my current drivers : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/276990

Thanks Squaredge. So can you confirm that installing linux-backports-modules resolved the issue as it did for bug 276990 . Assuming that is the case, we'll go ahead and just mark this as a duplicate of that bug. Thanks.

Since yesterday, No freeze (only 1 but between the package install and my reboot). Since this reboot, I've not freeze :)
I hope this will continue !

What exactly is this package ? Why is not include with kernel ?
Thanx a lot !

Thanks for the update. I'm marking this as a duplicate of bug 276990 .

Just to give you a little more information regarding linux-backports-modules . . . the purpose of the package is to typically provide post release updates to drivers. This helps avoid having to respin images etc. It's helpful as in your case because it can provide and alternative to users who need a slightly newer version of a driver. It's not installed by default because it should be an elective install and only used by those who need it. Usually the drivers provided in the main kernel should be sufficient and they also get more robust testing. But there's always the case, such as this bug, where we need to provide the newer drivers. Hope that helps. Thanks.

But how are those who need it supposed to know that they do? It's not
like this is a problem that can be easily traced to the wireless driver.

Hi Tom,

This issue was documented in the Intrepid Release Notes[1] so hopefully
some users can benefit from it's mention there and be directed to
installing the linux-backports-modules-intrepid package. Otherwise,
those who are involved with the triaging of these types of bug reports
can hopefully help direct bug reporters to try the package. Thanks.

I understand that this is the official position, but I can't say I agree
with it.

In any case, could you set the importance of this bug to Critical or
High, so that people affected by this bug will at least be able to find
the report.

Sorry about the upstream tracker, this should be assigned to
intellinuxwireless, not linux. I assumed launchpad would fill in this
information from the URL.
