When in this procedure did you get this panic() (the first or second reboot= )? If you are at a debugger prompt (db>) the output of 'trace', 'show pcpu', 'show pcpu 0', and 'show pcpu 1' would probably be useful to the kernel hackers who can help you (not myself). Thanks for helping to test the beta, and getting the information that will be needed to debug this. Ben Kaduk
