I'm running CentOS 5.3 on x86_64 platform with kernel version
2.6.18-128.el5 and having issues running kexec. I've got the kernel
built with CONFIG_KEXEC and CONFIG_CRASH_DUMP, and I'm booting with
crashkernel=64M@16M, but anytime I try to load a kernel with kexec I get
the following:
Invalid memory segment (nil) - 0x309fff
Did I miss something somewhere? I will provide any additional
information if needed.

ususally I see erors like that when you don't have sufficient memory reserved.
try bumping up your crashkernel allocation to 128M

I just tried crashkernel=128M@16M and also crashkernel=256M@16M and it
keeps giving me the same error. Shouldn't the (nil) actually be
something like 0x100000, corresponding to the 16M physical memory offset
of the kernel? Looking at my kernel config, it doesn't even have a
CONFIG_PHYSICAL_START setting available.
