Kernel panic in Intrepid Ibex (8.10)

[[e-mail]]

I'm running Intrepid Ibex RC on a Dell D830. The machine has locked up for at least 5 times this day (running for 3 hours now), with a blinking capslock and scrolllock. The kernel panics happen after boot, at random times. Never had a kernel panic during boot.

I have gathered some unformation and was able to take screenshots of the panics. I'm attaching them to this issue.

I did a memtest, but that did not find any issues.

Hi Hilbert,

I noticed in the last picture you attached there was some references to iwl3945 in the call stack. Care to maybe try installing the linux-backports-modules-intrepid package? The reason I ask is that it has an updated version of the compat-wireless stack so I'd be interested if it helps resolve these panics. Please let us know. Thanks.

I reinstalled all kernel packages, but this did not help. I had another freeze after 45 min.

I'm going to install the linux-backports-modules-intrepid package now.

[[e-mail] (hilbert-deactivatedaccount-deactivatedaccount)]

Unfortunalely, after installing the linux-backports-modules-intrepid I got another freeze around 18:00 hours. I'm attaching the kern.log that shows the logging until that moment.

Note that I was using wlan and the wlan itself had some problems. At times I could not connect to the wlan, at times I was connected, but did not have internet access. Others where experiencing the same problems. However, this should of course not crash the kernel...

Hi, I have also been getting random kernel panics since I installed Intrepid last week. This has never happened before in Feisty or Hardy on the same computer. I have a Intel 4965agn wireless card. There are no traces of the panic in any of the logs, as far as I can tell.

This is happening to me as well with the full release of Intrepid Ibex. Lights flashing, full lockup, and requires a hard boot. Let me know if you need any info from my system.

In the forum I read this might be helpfull:

Here is mine, not sure what someone can make of it, haven't had a crash in a couple hours this time though, but nothing was updated, so that wouldn't make any sense.

I'm not 100% certain, but I think this bug is a duplicate of #276990

https://bugs.launchpad.net/ubuntu/+bug/276990

[[e-mail] (hilbert-deactivatedaccount-deactivatedaccount)]

I'm not sure, since I have a different wlan chip, use a different module and am not using 802.11n

[[e-mail] (hilbert-deactivatedaccount-deactivatedaccount)]

This bug has not occurred any more, so it must have been fixed by new package versions.

[Leann Ogasawara (leannogasawara)]

Thanks for the note Hilbert. Can you comment which kernel version you are currently using just for anyone else who was experiencing this issue as well. However, since you are the original bug reporter, I'll go ahead and mark this Fix Released. If you do notice any regressions regarding this issue, please feel free to reopen by setting the status back to "New". Thanks.

I started getting this same problem today. My laptop has frozen in the past, although until today I'd never noticed the caps and scroll lock keys flashing. Today my laptop has frozen twice, and on both occasions those lights were flashing. I'm using the 32-bit version of Ubuntu 8.10 on a Dell Inspiron 1520. I'm using 2.6.27-7-generic with backports.

This is occuring for me, its happened twice since installing intrepid 4 days ago. I have attached my lspic and lsmod output.

[Michael Barker (mike-middlesoft)]

Lsmod information.

[Dr D J Clark (djc-online)]

This has started happening today after the recent security update to Network Manager.
Was working fine with Lenovo T61 and Intrepid since release in October but three times whilst using wireless connnection today.
