The problems I was having with a kernel panic after upgrading a Fedora Core 2 machine to Fedora Core 5 were entirely due to the SElinux support. I simply booted in linux rescue mode and disabled SElinux. Problem solved. I am currently updating all 1.2 Gb of rpms via yum at the moment. Is there a recommended procedure for re-enabling SElinux in this case (at least long enough to know it works). I am assuming that... touch /.autorelabel reboot is the best approach (although I assume I need to re-enable SElinux for the relabeling to occur). Jack
