+ help
+ This integer controls the behaviour of kdb when the kernel gets a
+ catastrophic error, i.e. for a panic or oops.
+ When KDB is active and a catastrophic error occurs, nothing extra
+ will happen until you type 'go'.
+ CONFIG_KDB_CONTINUE_CATASTROPHIC == 0 (default). The first time
+ you type 'go', you will be warned by kdb. The secend time you type
+ 'go', KDB tries to continue. No guarantees that the
+ kernel is still usable in this situation.
+ CONFIG_KDB_CONTINUE_CATASTROPHIC == 1. KDB tries to continue.
+ No guarantees that the kernel is still usable in this situation.
+ CONFIG_KDB_CONTINUE_CATASTROPHIC == 2. KDB forces a reboot.
+ If you are not sure, say 0.
