Thanks for reviewing Is it sounds good to add following line into section "Boot into System Kernel": The memory reserved for crash kernel should be no less than the unpacked init ram disk size that loaded with dump-capture kernel plus wired memory used by kernel itself. #

[PATCH 1/1 v1] the recommended crash memory reservation is too small for x86_64.

From: root On Documentation/kdump/kdump.txt, section Boot into System Kernel: On x86 and x86_64, use "crashkernel=64M@16M", but some OSes like ubuntu 12.10 use ram fs larger than 64M, so in these cases the memory reserved for crashkernel should be at least 128M. Signed-off-by: Zhouyi Zho
