Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description doesn't yet have enough information.
Please include as attachments the following additional information, if you have not already done so (please 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' 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!

dmesg.log

[Dennis_L (jf-lbrg)]

lspci-vvnn.log

[Dennis_L (jf-lbrg)]

my first post already includes the uname -a

[Brian Murray (brian-murray)]

Does that same thing happen if you reboot before logging in?

[Dennis_L (jf-lbrg)]

I've just tried and the same thing happend before logging in.

[Brian Murray (brian-murray)]

It'd be great if you could provide a kernel log like '/var/log/kern.log.SOMETHING' that covers a time frame when this happened. Thanks again!

[Dennis_L (jf-lbrg)]

I hope this is what you are looking for

[Brian Murray (brian-murray)]

I'm sorry but it actually isn't. Let's look at the '/var/log/kern.log*' files I have available on my system:

-rw-r----- 1 syslog adm 0 2008-08-12 08:49 /var/log/kern.log
-rw-r----- 1 syslog adm 1.8M 2008-08-11 07:47 /var/log/kern.log.0
-rw-r----- 1 syslog adm 269K 2008-08-10 08:11 /var/log/kern.log.1.gz
-rw-r----- 1 syslog adm 167K 2008-08-09 08:14 /var/log/kern.log.2.gz
-rw-r----- 1 syslog adm 285K 2008-08-08 08:10 /var/log/kern.log.3.gz
-rw-r----- 1 syslog adm 330K 2008-08-07 08:18 /var/log/kern.log.4.gz
-rw-r----- 1 syslog adm 306K 2008-08-06 08:32 /var/log/kern.log.5.gz
-rw-r----- 1 syslog adm 410K 2008-08-05 08:21 /var/log/kern.log.6.gz

You can see I have kernel log files back to August 5th, with kern.log.6.gz covering from 08-05 to 08-06. If you could include a log file that covers a time period where the crash happened that would help us a lot.

[Dennis_L (jf-lbrg)]

Well this is a kern.log with two failed start ups.
I've put some tags in the log when the pc freezes.

[monkeyking (glidecreme)]

I'm experiencing the same problem.
uname -a
Linux optiplex1 2.6.24-19-generic #1 SMP Wed Aug 20 22:56:21 UTC 2008 i686 GNU/Linux

[monkeyking (glidecreme)]

btw I'm also using optiplex 745,
I haven't had the problem until recently, that is the problem started somewhat after 8.04 upgrade.

[monkeyking (glidecreme)]

and the output for
cat /proc/version_signature > version.log
Ubuntu 2.6.24-19.41-generic

[monkeyking (glidecreme)]

I think this bug could be related to this one.

Hi Dennis_L,

I notice in one of your original comments you are running a Dell. Can you try booting with the 'reboot=b' boot option? Does this help resolve the issue you are seeing? Please let us know. Thanks.

[monkeyking (glidecreme)]

Hi, sorry I didn't inform you about that.
I've been using reboot=b for a long time,
so that is defnently not the solution.

The problem, with the computer, when i'm not using reboot=b.
Is that I was unable to do a proper restart using inet 6 or the like.
It was simply hanging after shutdown.

This problem also happens, (sometimes) just after the user logs out.
(gnome logout). So instead of seeing the login screen the computer just dies.

I'm unable to ping it after crash, so I's a kernel issue I think.

The only way to avoid the crash is not to logut and kill x explict, with the alt ctrl backspace.

[Spamfree (ubuntu-netryx)]

I also suffer from this issue. It appears to be triggered when Network manager loads. attached are my log files that all end at the hang.

[Leann Ogasawara (leannogasawara)]

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

[monkeyking (glidecreme)]

Hi,
I'm willing to try out the new kernel to see if it resolves the issues,
but can you elaborate on where to find the package.
It's in synaptic, so do I need to add something to my sources.list.

[Leann Ogasawara (leannogasawara)]

Sure, you'll need to enable the Intrepid repository in your sources.list file in order to install the 2.6.27 kernel. Or since Alpha5 was released last week you could also test using a LiveCD. Thanks.

I'm too experiencing the same problem and the reboot=b option is not the solution. The solution to this problem exist for this version or should I wait until the new version?

[monkeyking (glidecreme)]

I upgraded to the new kernel,
and it seems like it worked.
I added the ibex line to my sources.list,
then I updatet just the kernel part,
then I removed the ibex line from the sources.list.

I don't think this way of doing it is recommended though.

[zhang xuecheng (zhangxuecheng1985)]

i used to suffered in the same problom.
today i compiled a new kernel from kernel.org with version of 2.6.26,then reboot the machine,it works:)

[edwinfg (edwin-fg)]

Ok, thank very much. I have so many Live CD and we use these in class, I wait for the new release, thanks. :(

[Leann Ogasawara (leannogasawara)]

I'm marking this "Fix Released" for Intrepid. @Sven-Haegar Koch, thanks for the reference to the patch. I'll also open a Hardy nomination to try to get this backported as an SRU for Hardy. Thanks.
