Hello. I have the same problem ACPI_PSS bug is not letting me run live environment or installation of 9.10 or 9.04. I downloaded 8.04 LTS just to test and that runs fine.
I'm new to both Ubuntu and bug reporting, should I just report here or open new report with my motherboard model? In case you want to know, it is Gigabyte MA78G-DS3H, ver1.0. Factory BIOS was F3 and the error was present there. I updated to latest F8 and the error is still there. The error appears with both Cool&Quiet enabled (default) or disabled. Also, the error is still there even if I edit (with TAB) the command line of the Try Ubuntu option adding at the end "acpi=off noacpi". I saw that alternative in another post but doesn't help for me. So as far as it looks to me, I have two options: not install Ubuntu at all, or settle for 8.04. But I really want 9.10. Any chance of this "bug" being solved? If you need more info just ask for but consider the following: 1. I'm new to Ubuntu so you would need to provide steps (not too detailed, I can find my way around) 2. I do not have a running 9.10 or 9.04 system due to the error above so don't know how would I provide logs/files from it. I have a running 8.04 but that doesn't give the error which is why it could be installed. -- powernow-k8: BIOS does not provide ACPI -PSS objects in a way that Linux understands https://bugs.launchpad.net/bugs/364156 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
