Yeah! One last google search turned up another kernel argument to try. Using "nolacpi" with or without the other apic/acpi arguments finally gets rid of the errors and permits the FC5 kernel to boot! -Jim On 6/27/06, Jim Shepherd <jeshep@xxxxxxxxx> wrote:
I just updated to the "kernel-2.6.17-1.2139_FC5" kernel and am getting the following error: APIC error on CPU0: 02(02) This error repeats continually very early in the boot process. The system must be reset to gain control. From a google search, it seems that this error indicates a system error with the APIC communications. I have updated the BIOS to the latest version, disabled apic in the BIOS, and tried using the "noapic", "acpi=off", and "pci=noacpi" kernel options without any effect. As before, I can still boot successfully with any FC4 kernel. Why am I still getting these errors when it has been disabled in the BIOS and kernel, and only with the FC5 kernels? Any ideas? -Jim On 6/25/06, Jim Shepherd <jeshep@xxxxxxxxx> wrote: > Does anyone have any ideas on how I can debug this problem I am having > with the FC5 kernels locking up very early in the boot process?
