I know thats because of random bogosity coming in from the internet, and I really don't care. can I suppress that from filling up the dmesg buffer so I can see more important things like scsi soft errors?
You can filter these messages to their own log when using rsyslog and its regex features. I'm not sure how much performance impact you'd take from it, but unless you're a really high-traffic site, it should be just fine.
