This may # spit out thousands per second. # # For events of each level, you can choose to crash, report, or ignore. # TODO: allow choice based on the facility: e.g. crash on panics from # everything except the cdrom, and only report those. # # If you are experiencing many panics, it can be helpful to change # the panic action to report instead of fatal. However, be aware # that anything executed after a panic is uncharted territory and can # cause bochs to become unstable.
