This is with Ubuntu 7.10/amd64 on dual core AMD Athlon with 4GiB RAM. Xen 3.1 is used as hypervisor, but there is only a single domain.

This seems to be related to bug 163952 (occurred on the same machine yesterday).

The system is still running, but some processes 'hang'. Rebooting now ...

Hi Guenthert,

The Hardy Heron Alpha series is currently under development and contains an updated version of the kernel. It would be helpful if you could test the latest Hardy Alpha release: http://www.ubuntu.com/testing . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. Thanks.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

[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.

This bug report is being closed because we received no response to the previous request for information. Please reopen this if it is still an issue in the actively developed pre-release of Jaunty Jackalope 9.04 - http://cdimage.ubuntu.com/releases/jaunty . To reopen the bug report simply change the Status of the "linux" task back to "New".
