Hi,

APIC is a feature, a new one to support better IRQ handling on the mainboard.
Normally its a Chip included in the chipset. Sadly some/most BIOS vendors do not
support APIC, so sometimes when Linux uses APIC it ends in strange/unstable 
behavior.

Just try to boot your kernel with the option "noapic", if it helps you
are lucky.

in the first cols, are number beyond 15, so APIC is enabled.
