Oh. Actually, the difference is that the other machine was running a
kernel without DIAGNOSTIC/DEBUG. (They were also slightly different
revisions of the sources, originally, but that wasn't a factor.)
This time it's stopped in init instead of a python, FWIW:
panic: kernel diagnostic assertion "pmap->pm_obj.uo_npages == 0" failed: file
"../../../../arch/xen/i386/pmap.c"
