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
------------[ cut here ]------------
WARNING: at arch/x86/kernel/apic/apic.c:1299 setup_local_APIC+0x22c/0x2e2()

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

Sorry for pasting some of the dmesg output, I've attached a log...

THANKS

[DasFox]

SORRY guys, false alarm, I removed these;

Symmetric multi-processing support SMT (Hyperthreading) scheduler support

Now I'm no longer getting the warning.

I do see other possible issues, so please see attached file; dmesg_2.log

THANKS

Hi,

Sorry, don't mean to rush anyone, I just need to get a clean image with everything worked out for my business, so for the dmesg_2.log, the errors in it, I'd appreciate if it someone can tell me as soon as possible how I can correct those?

THANKS, I really appreciate it! :)

Hi,

I was able to recompile the kernel and figure out a few things, these are all that are left that I don't know;

• Fast TSC calibration failed
• TSC: Unable to calibrate against PIT
• TSC: using PMTIMER reference calibration
• Performance Events: Broken PMU hardware detected, using software events only.
• Enabling APIC mode: Flat. Using 0 I/O APICs
• APIC calibration not consistent with PM-Timer: 101ms instead of 100ms
• APIC delta adjusted to PM-Timer: 6296145 (6368174)
• platform rtc_cmos: registered platform RTC device (no PNP device found)
• audit: initializing netlink socket (disabled)
• type=2000 audit(1325101768.517:1): initialized
• input: Unspecified device as /devices/virtual/input/input4

Again, I'd really appreciate some help here, I don't know if these are bugs, or something I can fix...

THANKS
