Is This A APIC Bug?

[DasFox]

I'm running Slackware 13.37 as a Guest in VB 4.1.4 and I noticed in /var/log/dmesg this;

weird, boot CPU (#0) not listed by the BIOS. SMP motherboard not detected. Enabling APIC mode: Flat. Using 0 I/O APICs

So between also this 'weird, boot CPU' and the APIC warning I wanted to know if this is a bug?

I also don't like using the standard kernel in Linux, to make things that are not supported that you have to weed through all the messages to figure out what is going on, so I compile my own kernel.

These are some of the options I compiled in below. Also are there any other options I need to make sure I have support for in the kernel for VirtualBox, specific to it?

<*> Intel PIIX4 and compatible (ATI/AMD/Serverworks/Broadcom/SMSC) <*> EHCI HCD (USB 2.0) support <*> USB Mass Storage support [*] ISA support

Processor type and features --->

[*] Tickless System (Dynamic Ticks) [ ] High Resolution Timer Support [X] Symmetric multi-processing support (keep this enabled for multiple cores, too!)

Subarchitecture Type (PC-compatible) --->

[ ] Machine Check / overheating reporting [X] SMT (Hyperthreading) scheduler support (This too, for i7's)

Power management and ACPI options --->

[*] Power Management support [ ] Suspend to RAM and standby [ ] Hibernation (aka 'suspend to disk') [*] ACPI (Advanced Configuration and Power Interface) Support --->

Device Drivers --->

< > ATA/ATAPI/MFM/RLL support <*> Serial ATA and Parallel ATA drivers

<*> AHCI SATA Support [*] ATA SFF support <*> Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support

[*] Network device support --->

[*] Ethernet (10 or 100Mbit) --->

[*] EISA, VLB, PCI and on board controllers

<M> AMD PCnet32 PCI support

[*] Ethernet (1000 Mbit) --->

<M> Intel(R) PRO/1000 Gigabit Ethernet support

[ ] Ethernet (10000 Mbit) --->

Input device support --->

[*] Mice --->

<*> PS/2 mouse

Graphics support --->

<*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) --->

< > all options can be empty

<M> Sound card support --->

<M> Advanced Linux Sound Architecture --->

[*] PCI sound Devices --->

<M> Intel/SiS/nVidia/AMD/ALi AC97 Controller
