>Description:
Booting installed system with corrupted rtc (cause not known, but not FreeBSD related).

The boot process fails because the rtc is invalid, and then reboots endlessly.(no dump device)

This needs to be changed so that the user is offered the choice of having the rtc zapped to a sane state for subsequent resetting after reboot. Present strategy leaves system undecoverable.
>How-To-Repeat:
You would need a way of corrupting the rtc!
>Fix:
change the code so that on detecting rtc is corrupt, ask user if he wants it zapped.
