At the risk of angering the crash Gods, my sustem has NOT crashed again since I downgraded the kernel from 2.6.18-1.2239.fc5 to 2.6.18-1.2200.fc5. Given that newfound stability, and my lack of time, I'm going to put on hold any further diagnostics, until the next kernel revision is released. I have submitted a report at bugzilla.redhat.com (bug 218128). (Ah, nuts; accidentally created a duplicate at 218129 also. Sorry about that). Uh, does anyone have a Fedora Core 5 kernel Changelog from 2200 to 2239, so I can figure out what fixes I'm *not* running right now, as a result of my backing off from 2239 to 2200? Heh. Thanks! -Jay
