I thought this was by design, I've noticed it very early (7.x, probably 
earlier) and just thought that when lot of data is written to the 
console, the actual kernel message buffer gets invalidated or freed. 
This made me stop using dmesg altogether and just look at either 
/var/run/dmesg.boot for the boot messages or /var/log/messages.
