Description (last modified by frank) (diff)
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() Hardware name: VirtualBox Modules linked in: Pid: 1, comm: swapper Not tainted 3.1.5 #1 Call Trace: [<c102fb37>] warn_slowpath_common+0x6a/0x7f [<c13119c9>] ? setup_local_APIC+0x22c/0x2e2 [<c102fb60>] warn_slowpath_null+0x14/0x18 [<c13119c9>] setup_local_APIC+0x22c/0x2e2 [<c148fb2c>] APIC_init_uniprocessor+0x94/0xe9 [<c148db9f>] native_smp_prepare_cpus+0x1d1/0x3b8 [<c148569b>] ? start_kernel+0x2e3/0x2e3 [<c14856d7>] kernel_init+0x3c/0xfd [<c13163fe>] kernel_thread_helper+0x6/0x10 ---[ end trace a7919e7f17c0a725 ]--- APIC calibration not consistent with PM-Timer: 145ms instead of 100ms APIC delta adjusted to PM-Timer: 6289924 (9125077)
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?
