Kernel Debugging Options

Hello everyone
I have a two-part question:
I have a minimally customized GENERIC kernel, with the only changes being:
options KDB
options KDB_UNATTENDED
options DDB
and 'sysctl debug.debugger_on_panic' shows:
debug.debugger_on_panic: 0
However, after a panic loading the vboxdrv.ko module, the machine did
not reboot automatically after reboot.
Here are my questions:
1) Would enabling DDB in the kernel prevent an automatic reboot after a panic?
2) Does the debugger wait for XX seconds of console inactivity before
rebooting? I was under the impression from the handbook that the
machine would instantly reboot and after dumping the crash to vmcore0.
Is this assumption incorrect?
Thanks in advance for any input.
