Comment 2 for bug 314530

Hi Alex, thanks for filing this. Can you please also add the following as separate attachments?

 * Output of sudo dmidecode (attach dmidecode.txt)
    sudo dmidecode > dmidecode.txt
 * Try to suspend/hibernate and then restart the system and attach /var/log/kern.log.0
 * Tarball of /proc/acpi directory. You can't just tar all files because their content sometimes changes etc.
    cp -r /proc/acpi /tmp
    tar -cvjf ~/acpi.tar.bz /tmp/acpi
then attach acpi.tar.bz from your home directory

Also, please let us know when you are seeing these errors exactly. If you are having trouble booting, can you also please try the steps in section 2.1 "Debugging procedure" at https://wiki.ubuntu.com/DebuggingACPI - particularly the parts about APIC (not the same thing as ACPI).

Thanks in advance.
