Wireless instability with 2.6.32-24 on HP G62

[Jon]

Binary package hint: linux-image-2.6.32-24-generic

== Notes ==
Hardware is an HP G62 Laptop. On 2.6.32-21-generic, the wireless was rock solid. Once the machine was upgraded to 2.6.32-24-generic, the wireless became unstable. Every few minutes the connection simply drops outs for a few seconds, then re-establishes itself. This is not due to a lack of signal from the AP, the location is the same before and after and there are two Cisco AP's nearby and provide good strength.

Syslog section copied from when the wireless drops & reconnects.

Hi Jon,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please 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 628345

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.

Same issue on Asus 1201T Netbook with this device as of today, and actually with the -25 kernel from ubuntu Lucid, it seems to be worse...

Driver might keep connection for 5 minutes or 5 hours, but when the device fails, it must be rmmod'ed and modprobe'd and network manager must be restarted in order to reestablish a connection. I had created a script linked to an icon because this happens so frequently.

I found issues relation to memory leak issues for those running more than 4 GB but I have only 2 GB.
