Syslog question

[R Kimber]

If I try to diagnose a problem by looking in /var/log/syslog I'm confronted
mostly with messages of the form:-

<time> <host> [425828.266000] status interrupt: 80 02

My current syslog contains 792,386 of such messages.  They appear to be
logged about 30 times a second.

Is this a bug?  It certainly makes solving problems more difficult having
to sift through all this stuff.

If it's not a bug, how may I stop the messges from being logged?
