[I got a boot-time panic with a debug kernel that
reported a "acquiring blockable sleep lock with
spinlock or critical section held (sleep mutex)".
This was for data_abort calling pmap_fault calling
__mtx_lock_flags . I first include prior non-debug
kernel reports in case they are related.]

[Another issue was modern boot1.efi (as bootaa64.efi)
not working and so I'm using an old one (2016-Nov-7)
that I found that allows getting this far.]
A boot attempt with a older boot1.efi that works and a
debug kernel got:
