security run output question (GEOM: create disk)

[Duane Winner]

Hello,

Does anybody know what this means when I see this in a daily security 
run output?:

locahost.local kernel log messages:
GEOM: create disk ad0 dp=0xc6b77d60
GEOM: create disk cd0 dp=0xc69a8600


I don't recall ever seeing this in my daily outputs, but my boss sent me 
an email with this and he wants to know what it means.

If I do a 'dmesg' on my computer, I also get:
GEOM: create disk ad0 dp=0xc6b63160
GEOM: create disk cd0 dp=0xc6983e00


What does this mean, and what does it mean when it shows up in the 
security run output?

Thanks for any info.
