Go to http://gaugusch.at/kernel.shtml and download the initrd-add-dsdt script. Do something like:
cd /boot /usr/bin/iasl -tc <your dsdt dml file> cp initrd.img-2.6.20-16-generic initrd.img-2.6.20-16-generic-dsdt initrd-add-dsdt initrd.img-2.6.20-16-generic-dsdt dsdt.aml Then change your grub menu to point to the new initrd.img file: initrd.img-2.6.20-16-generic-dsdt I tried this, however I still get the errors. You can confirm you dsdt changes by looking at what's in: /proc/acpi/dsdt after rebooting with the new initrd -- Power states AMD64x2 broken https://bugs.launchpad.net/bugs/147762 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
