Bryan, This sounds like a Athlon and AGP graphics and Linux 2.4 kernel issue that Anne Wilson pointed out to me just the other day. See the following URL's provided by Anne that explain the problem with varying detail; http://www.vnunet.com/News/1128504 http://linuxtoday.com/news_story.php3?ltsn=2002-01-21-001-20-NW-KN http://www.geocrawler.com/lists/3/Linux/35/175/7626960 http://www.theregister.co.uk/content/3/23826.html In the end, it looks like rebooting the system with "mem=nopentium" may solve the problem. mike On Mar 5, 2:24pm, Bryan G.
