I just tried crashkernel=128M at 16M and also crashkernel=256M at 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.
