Unfortunately there are just, flat-out, way too many kernel messages at
boot-up. Making them KERN_DEBUG doesn't solve the fact that SMP boxes
often overflow the printk buffer before you boot up to a useful userland
that can record the dmesg.

The IO-APIC code is a _major_ offender in this area, but the CPU code is
right up there as well.
