And my second question is, if not, how do I get rid of them? I'm thinking it is some kernel option, but I can't seem to find it.

I added the following "kern.!warning" to the rsyslog.conf file, so that the following lines looked like this: Code: .;auth,authpriv.none,kern.!warning -/var/log/syslog kern.*;kern.!warning -/var/log/kern.log That got rid of the warnings that were filling up my logs.
