Public bug reported: I have been unable to successfully boot Ubuntu (10.10, 11.04, 11.10 23bit and 64bit) unless the acpi=off setting is referenced at boot time. The screen will generally go black and leave a blinking underscore cursor in the top left hand of the screen. I have been able to boot other distributions of Linux but these have used much older kernels.
I have followed advice on several forum pages regarding similar issues but none of this has resolved the issue. Attempting to boot with "verbose" and "text" parameters does not provide any further hints as to what may be causing the problem, there is text shown on the screen but the boot hang does not always occur at the same place, so this is inconsistent. I have also followed the debugging guidelines on https://wiki.ubuntu.com/DebuggingACPI but again the only thing that works is the "acpi=off" parameter. I have replaced the motherboard and the processor but neither of these has resolved the issue. What I would expect to happen is for Ubuntu to boot correctly without the need to either manually specify boot parameters at the grub menu or to have to update the grub config (/etc/default/grub). --- AcpiTables: AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
