Use this screen to select whether or not to use Kdump on this system. Kdump is a kernel crash dumping mechanism which, in the event of a system crash, captures information that can be invaluable in determining the cause of the crash.
Note that if you enable Kdump, you must reserve a certain amount of system memory for it. As a result, less memory is available for your processes.
If you do not want to use Kdump on this system, uncheck Enable kdump. Otherwise, set the amount of memory to reserve for Kdump. You can let the installer reserve a reasonable amount automatically, or you can set any amount manually. When your are satisfied with the settings, click Done to save the configuration and return to the previous screen.
