Bug Description

These kernel warning started to happen pretty consistently after every reboot somewhere during the lucid alpha cycle and have not stopped since. I just realized that there might be a connection to a regression with gobi_loader (the firmware loader for the internal gobi WWAN chipset of this notebook): https://bugzilla.kernel.org/show_bug.cgi?id=15134

While the WWAN module worked in Karmic without problems, it fails in Lucid.

Now, the kernel problem reported here could be the cause or could be the effect of this.

Hi michael.huettemann,

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 556317

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.

[This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

I just tested with this mainline kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-lucid/linux-image-2.6.34-020634-generic_2.6.34-020634_amd64.deb

The problem remains the same.

I'm seeing very similar (identical?) behavior. For me, the problem seems to occur almost immediately when the device (an ftdi FT232RL) is opened. Reinserting the device often seems to resolve the problem.

This particular device spews a very large amount of data at 230.4kbps, beginning the moment the device is opened. (Perhaps this is helpful info?)
