Bug Description

Binary package hint: linux-image-2.6.22-14-xen

The console for a domU kernel freezes on "Setting system clock"

This occurs for every ubuntu gutsy (and maybe others) domU, unless you add exit 0 (or some other workaround) to /etc/init.d/hwclock.sh
and /etc/init.d/hwclockfirst.sh.

I'm not sure yet if it's just the console or the domU itself which freezes. Seems to be the latter, but I can't be sure.

According to Stephen Seitz:
This issue is caused by an ubuntu domU kernel patch which uses the clock
of the hostsystem.
I did some similar by chmod 000 /etc/init.d/hwclock*
which isn't a clean solution but works also.

A clean solution would be to patch the hwclock scripts to look for e.g.
/proc/xenbus . I would file a bugreport, but I assume I'm unable to handle
launchpad.net ...

I have confirmed this bug. Adding exit 0 to /etc/init.d/hwclock.sh does solve the issue but something more graceful would be nice.

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!

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.
