With "after reboot" do you mean a power off, power
on cycle?
Core memory is critical while power off/on.
If power fails after the read cycle and before
the refreshing write cycle then the contents is lost.
So maybe you have problems with the power supply or
the power fail logic.
Just my 2c

Several locations which I've checked seems to be losing content (core is
supposed to be non-volatile). I've been debugging custom bootloaders
for the past week and it has since gone past annoying. It's like 3
locations out of 50 that are always reverting back to 000000 after a
reboot.
Perhaps it's the driver logic to these 3 particular cores that are not
functioning properly? Or is it the cores itself?
