can you please boot using:

expert acpi=off

and see if it still happens?

Thanks
Fabio

[Fabio Massimo Di Nitto (fabbione)]

For the record, i just received this mail from the submmiter:

"I tried what you told me with expert acpi=off and it worked out just
fantastically."

Matthew do you want to take over and take a look please?

Thanks
Fabio

It's rebooting during kernel startup. Bit hard to track this down - it's
possibly fixed in the 2.6.12 acpi code. When we have a 2.6.12 Colony CD, that
ought to help us get an idea as to where we stand.

[Matthew Garrett (mjg59)]

Could you possibly try with Colony 3 from
http://cdimage.ubuntu.com/releases/breezy/colony-3/ ?

[Chuck Short (zulcss)]

No response from user, assuming fixed.

I'm new to launchpad, didn't see to change status with last comment

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 linux-source-2.6.15 kernel bug to the new "linux" package. We appreciate your patience and understanding as we make this transition. Also, if you would be interested in testing the upcoming Intrepid Ibex 8.10 release, it is available at http://www.ubuntu.com/testing . Please let us know your results. 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.
