I played around with the kernel debug options a little and found peculiar=20
things:=20

=2D With just options KDB (and no debugger backend specified), a panic will=
 just=20
cause some output scroll very fast on the console - perhaps kdb is trying t=
o=20
enter a nonexisting debugger backend and loops?

=2D With options KDB, KDB_UNATTENDED and DDB, a panic _does_ trigger DDB,=20
contrary to what the description of KDB_UNATTENDED says.

It seems to me 5.3's debugging facilities are somewhat in disarray...

=2D-=20
