This option allows system calls to be traced to the console. It also
|
||
|
|
aids in detecting kernel stack underflow. It is useful for debugging
|
||
|
|
early-userland problems (e.g. init incurring fatal exceptions.)

If you say Y here the resulting kernel image will be slightly larger
|
||
|
|
and slower, but it will give very useful debugging information.
|
||
|
|
If you don't debug the kernel, you can say N, but we may not be able
|
||
|
|
to solve problems without frame pointers.
