* uname -a > uname-a.log
* cat /proc/version_signature > version.log
* sudo lspci -vvnn > lspci-vvnn.log

Sorry, i don't know, where these files are.

I cann't say that i do something special when system hangs. Sometimes it hangs when i download upgrades (or simply using internet), sometimes - when i watch video or just even read Open Office document. I have 2.6.20-15-generic kernel installed on my laptop - and it works perfect, so i'm sure that it is not a hardware problem, it hangs ONLY under 2.6.24-2-generic kernel.

Thanks Kamba. After you notice the system hangs and you have to reboot, can you then attach your /var/log/kern.log.0 file? Thanks.

patch this bug, i think it is critical, when system just hangs randomly.

Why the status of this bug is Incomplete? Is there more information needed?

Care to retest with the latest 2.6.24-5.9 kernel and verify this issue still exists? Thanks.

In 2.6.24-5 kernel its still exists. I checked it.

In 2.6.24-8 still exists.

If you need some logs or files - just ask. I want it fixed!

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.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

Please upgrade to a current (Jaunty/9.04) Ubuntu release. If the problem persists, please open a new bug with logs and traces from the newer release for us to diagnose the problem. This bug on the older kernel is closed.
