From: Cliff Wickman <[email protected]> The crash kernel's boot command line is not long enough to contain the necessary memmap= options for a large memory.
The fix is simple, as long as the boot loader's command line is also long enough. I'm not sure about boot loader or kernel restrictions to this length.
