I started by testing vanilla 4.15-rc4 with a vm that has several memory
slots already populated at boot. With that I no longer get an oops,
however while /sys/devices/system/memory/*/online is 1 it looks like the
memory isn't being used. With your patch the behavior is the same. I'm
attaching dmesg from both kernels.
