I can confirm that changing the debug settings makes the difference
between booting and crashing.

However, trying to narrow it down to a particular config option is
proving tricky.

At first I thought that just turning CONFIG_DEBUG_SPINLOCK on stopped
it crashing, however further checking was inconclusive. My suspicion
is that it's things being moved around in memory as a result of code
being enabled that's the issue.

I'll continue investigating.
