Are you sure? I can't speak for safemode, but doing something like: [22:43:47]rml@phantasy:~$ mpg321 /home/mp3/Get_Up_Kids-Woodson.mp3 & [22:52:03]rml@phantasy:~$ dbench 16 I don't get any blips (nothing over 0.5s, anyhow, I would wager). This is a P3-733, i815 board, 384MB PC133, AHA-2940U2W, U2W IBM 9GB system. Linux 2.4.9-ac14 + preempt + and more -- Robert M. Love rml at ufl.edu rml at tech9.net
