Syslog says= qozap: dropped audio card 1 cardid 0

Hi

I have small * box,
CLI> show version
Asterisk 1.2.4-BRIstuffed-0.3.0-PRE-1k built by root @ [hostname] on a i686 running Linux on 2006-04-10 09:21:25 UTC

there is automated backup on dvd in crontab
when growiso is executed syslog gets:

kernel: qozap: dropped audio card 1 cardid 0 bytes ...
then i run cmp to compare burned file with original and kernel: qozap: dropped audio card 1 cardid 0 bytes ...
is present again

Anybody know how to ged rid of this ?
thanks
