Dell Insprion 13 lock up

[Sean-O]

At first I thought this was a Firefox specific bug, because when downloading a large file my inspiron 13 froze up, kernal and all, leaving the display as it was but both the caps lock and scroll lock LED's flashing once a second, and the wifi LED each half second. I would reboot, open firefox and resume the download and after a minuet or so it would lock up again.

This same lockup has just repeated itself while updating 8.10 64 bit from a scratch install, (223 updates).

This same thing happened on the same laptop using the 32 bit ver. of intrepid, however has not presented itself on my desktop runing the same kernel and downloading the same 223 updates.

the only way to re-gain control is to do a hard shutdown and reboot the system, where as everything is fine.

Marked time in system log and re-downloading updates to see what it has to say.

Did you use WiFi?
Maybe it does not occur when you use a wired internet connection.

[Sean-O (kain000)]

Yes it only seems to happen using wifi, however when re-downloading the
same updates, it completed without issue.

Alright scratch the original idea, I am pretty sure this is a blue tooth related error. The system logs always make alot of noise about bluetooth at the time of lockup. I have de-activated the bluetooth daemon and it has yet to crash again. simply switching off the radio didnt correct anything, and seemed to cause a greater frequency of lockups. why the lockups cause the caps lock and num lock to flash I dont know. Would you like me to post up my system log file?

[Martin Kossick (hacktick)]

I am not sure if I can help but this information could be useful.

[Sean-O (kain000)]

Update:
Bluetooth daemon is turned off and system just froze again for the first time. This time the trigger was a large download. the system log had alot to say about wlan0 up to the lock up.
I am including the last few lines from the message system log and the kernal system log. If anyone who knows more about this than I would like a longer log just shoot me an email.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it without more information.

Please include the following additional information, if you have not already done so (pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.

For your reference, the full description of procedures for kernel-related bug reports is available at https://wiki.ubuntu.com/KernelTeamBugPolicies Thanks in advance!

Alright, sorry for the incorrect formating, thankyou for the links.

alright I will attach the required information.

Is it possible to attach more than one file at a time?

[Sean-O (kain000)]

I really can only offer conjecture here as I am just starting to get my hands dirty with the kernel, but this doesnt seem to be just a single cause.

As I stated in my previous posts, the system would lock up upon a long download or just doing nothing at all. From what I could make out in the system logs it would spit out a bunch of lines about bluetooth before the lock up. I turned off the bluetooth daemon and that seemed to fix it, no lock ups for about 1 week, but then a few days ago it happened again while a package mannager was downloading alien arena from the repos.

The logs mention the device wlan0 alot and network info up to the lockup.

I dont thing this is triggered solely by a large download however, because When trying to replacate the lockup of the same large download it completed just fine.

I hope this helps, I want to help make Ubuntu the strongest OS out there, just tell me what I can do.

Sean-O: The most recent kernel for intrepid is 2.6.27-11 - can you update to that kernel and see if you still have the issue.

[Sean-O (kain000)]

Alright, Just updated and I will get back to you if and when it locks up
agian. Thankyou.

Alright update:
since update to kernel 2.6.27-11 the problem has yet to emerge again, this seems to have solved it, Bluetooth was not the cause and I am unaware what the real problem was but it apears solved.

thanks everyone.
