I have all possible debugging turned off. Heavy disc activity like untarring triggers the symptoms, which sounds like buffer underruns on the soundcard. Almost sounds like a new ATA stack is really effective (leaving little CPU cycles for feeding data to soundcard). -- Pav Lucistnik <pav_at_oook.cz> <pav_at_FreeBSD.org> In God we trust.
