This Elitegroup K7VZA 3.0 motherboard has a 686B Southbridge Chip in KT 133A Chipset that has a pci latency bug which leads to data corruption on IDE Disks and/or jitter in sound output (http://lists.suse.com/archive/suse-linux-e/2001-May/0759.html).
There is a workaround since kernel 2.4.4 (http://lists.suse.com/archive/suse-linux-e/2001-May/0783.html) and firmware upgrade to version > 3.4 helps too.
It works well for me.
