NOTICE:u79n:Abnormal interrupt! int_status=FC67C0D0

I am receiving the message of "NOTICE:u79n:Abnormal interrupt! int_status=FC67C0D0" periodically on my server. (version is 5.06) It is not creating a critical problem and my applications are running withouth any problem. What is the reason of that and how can I solve that problem?

Where do you receive these messages ? In the syslog ? Usually those messages are logged at the debugging level, if they are pain for you, then disable logging of "kern.debug". Also, what is your OS ?
