These types of problems are generally caused by: 1. Bad memory 2. Overheated processor, or some similar CPU fault 3. Bad memory > 1) Some time ago KDE was hanging in disk wait state forever.

BIOS "tests" don't count. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
