Asus A6000 (A6KT) fails to boot from CD-Rom (6.06 LTS)

Does that happen with the last ubuntu CD as well?
You can find the isos at http://www.ubuntu.com/getubuntu/download

The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Hardy Heron. It would help us greatly if you could test with it so we can work on getting it fixed in the actively developed release. You can find out more about the development release at [WWW] http://www.ubuntu.com/testing/

We are closing this bug report because it lacks the information we need to investigate the problem, as described in the previous comments.

Reopening, as this is still a problem on my A6KT ASUS notebook. Have attached more information in my comment.

The specific problem with this notebook is that if anything is plugged into a USB port, it will not boot.

The problem appears to be related to a buggy DSDT. I disassembled my original DSDT using Intel's iasl compiler/decompiler from http://www.intel.com/technology/IAPC/acpi/ and instructions from http://forums.gentoo.org/viewtopic.php?t=122145 . The instructions basically were:

cat /proc/acpi/dsdt > dsdt.dat
./iasl -d dsdt.dat

I have a "fixed" DSDT.aml which I have loaded via initramfs-tools and which fixes the problem as far as I can tell, but this shouldn't be necessary as Windows loads fine. The fixed DSDT.aml was obtained here: http://acpi.sourceforge.net/dsdt/view.php?id=735 .

I have attached the original disassembled dsdt.dsl, as well as the same file after loading the 'fixed' DSDT.aml using initramfs-tools / initrd method, and confirming that the notebook boots with a mouse plugged in.

There are some obvious differences between the original (broken) dsdt.dsl and the 'fixed' dsdt.dsl from my quick look, but I don't know enough about ACPI to know what's going on. Hopefully this can be pushed upstream for resolution?

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.

The clearly appears to be a BIOS issue.
