However that does give me some questions: If the extra hacking was done, what would be wrong with that occurring at the end of the reboot process, rather than the start of the boot process? If there's some form of a kernel panic then presumably a reboot would occur causing this hang; what could I do to prevent this? Are their any other times where a reboot could occur out of my control?
