Although I agree with your "too verbose" sentiment above, I think the
removing the messages outright might not serve the best interests the
developer. Since even KERN_DEBUG still spams dmesg, in these situations
I usually change these type of messages to be conditionally printed iff
a debug macro is enabled.
As a tangent, the huge x86 IO-APIC verbosity really bugs me, too, and
often is the direct cause of useful early printk messages being lost
before boot is even complete.
