ACPI is the successor/combination of plug & play, advanced power management, et al... If you have disabled ACPI and it did not make a difference, I would say the clue it's giving you is ACPI is not causing the error. APIC, on the other hand, has to do with interrupt timing. Do you see any options in your BIOS for enabling/disabling/changing APIC's slices or timing? Are you overclocking your RAM or CPU[s]? -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
