help decode my dmesg output

[TheCoop]

I have a few puzzling things on my dmesg which i could use your help in decoding:

<System>

All the APIC messages refer to the fact that your kernel probably has "Local APIC support on uniprocessors" enabled.

From the kernel source:
"A local APIC (Advanced Programmable Interrupt Controller) is an integrated interrupt controller in the CPU. If you have a single-CPU system which has a processor with a local APIC, you can say Y here to enable and use it. If you say Y here even though your machine doesn't have a local APIC, then the kernel will still run with no slowdown at all. The local APIC supports CPU-generated self-interrupts (timer, performance counters), and the NMI watchdog which detects hard lockups.

If you have a system with several CPUs, you do not need to say Y here: the local APIC will be used automatically."

Shouldn't be an issue one way or the other. I've disabled it on my system.
