Bug Description

I've been getting firmware errors with the iwlagn module recently. (Will they never go away?) After getting some firmware errors, I did 'modprobe -r iwlagn; modprobe iwlagn' to recover, and I got a segmentation fault.

Furthermore, on occasion after having a firmware error and reloading the module, my computer will freeze when I try to reconnect to the network.

I've attached my dmesg output. I'm running Intrepid.

I have had at least one kernel panic. However, the freeze that I get is often not a complete freeze. I can minimally interact with X, bringing up menus and such, but I can't start programs or switch to a virtual terminal.

Next time this problem rears its ugly head, I'll see what I can pull off the computer. This happens nearly daily, so I'll have more info soon.

I'm continuing to get firmware errors, but my computer hasn't become unresponsive. I'm posting a new dmesg full of firmware errors. My network came back up without prompting after each error.

It may be that the freezing issue is gone. I'll give it a few days time to be sure.

Well the freezing issue isn't gone, but if the firmware errors are fixed (another bug) then they're a non-issue.

Can you also confirm this issue exists with the most recent Karmic Koala 9.10 Alpha release? ISO CD images are available at http://cdimage.ubuntu.com/releases/karmic/ . If the issue remains with Karmic it would be great to then also test the latest upstream mainline kernel available. This will allow additional upstream developers to examine this issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Thanks in advance.

Please re-open this bug if this is still and issue in Karmic.
