kdump.conf was setting crashkernel out of laziness I assume. It didn't
override the default boot parameter. It did set maxcpus to 1.
KDUMP_CMDLINE="`cat /proc/cmdline` maxcpus=1"
I've changed it to this which gets rid of the crash dump allocation
failure and cma allocation failure (reduced cma from 1G to 128M):
KDUMP_CMDLINE="`cat /proc/cmdline` maxcpus=1 crashkernel=0 cma=128M"
But the result is the same:
