iwlagn wifi does not work with 4GB RAM in 8.04 LTS x86_64

[Peter Watkins]

I have an Intel-based laptop that's been running 8.04 LTS no problem for a year, with 2 GB of RAM installed. I replaced both RAM modules to upgrade to 4GB of RAM, tested with memtest86+ (several full passes, no errors), and then booted into 8.04 LTS again. The wireless (iwlagn) does not work with 4 GB of RAM in Ubuntu 8.04 LTS x86_64 (but works fine in 32-bit Windows Vista and 32-bit Ubuntu 9.10 -- so the hardware clearly is capable of using wifi with 4GB of RAM).

$ lsb_release -rd
Description: Ubuntu 8.04.4 LTS
Release: 8.04
$ uname -a
Linux stealth 2.6.24-27-generic #1 SMP Mon Feb 22 18:17:28 UTC 2010 x86_64 GNU/Linux
$ cat /proc/version_signature
Ubuntu 2.6.24-27.67-generic

Two more data points:

1) Works fine with 4 GB RAM if I run 9.10 x86_64 from a live thumbdrive:

$ uname -a
Linux ubuntu 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux
$ cat /proc/version_signature
Ubuntu 2.6.31-14.48-generic
$ lsb_release -rd
Description: Ubuntu 9.10
Release: 9.10

2) Works fine with 3 GB of RAM with my 8.04.4 LTS x86_64 installation.

Hi Peter,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 539369

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
