I'm seeing this one too. It seems to be triggered by udevplug (at least that's what the backlog seems to suggest).

I managed to get past this by loading necessary modules by hand, but i'm unfortunately stuck in partman not willing to acknowledge my partition scheme so far :P

The partman bug I'm seeing is #37970, I used the work around described in this bugreport. I'm attaching the logs of the installer, saved right after base-system install, hope that helps.

the bug is in the kernel and needs to fixed there. udevplug just triggers it. probably the others are just fallout of this one.

I isolated this down to 1 of 2 patches 'Reverting reverted acpi patch' in the 2.6.15-15 -> 2.6.15-16 abi change timeframe, with a 4100 line diff. Turning on CONFIG_ACPI_DEBUG masks the issue, so we've done that for now until we can figure out what part of acpi intel and the kernel disagree on.

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.
