Today we tried updating an i386 Fedora Core 2 workstation to Fedora Core 5. The upgrade install completed without complaint until we rebooted the machine. At that point I got a kernel panic with the message... Kernel panic - not syncing: Attempted to kill init. ...after the line stating that the kernel is being uncompressed and booted. What is the best approach to debugging this and is there specific set of causes for this problem? Jack
