Curses. When I tried to reproduce this, the machine booted with my default
config but died before initialising the console with your config. The machine
is far away so I can't see the screen or restart the machine remotely so
I can only assume it is dying for the same reasons yours did.

It would not have helped in this case because the zone boundaries would still
be in the wrong place for ia64. Below is a patch that aligns the zones on
all architectures that use CONFIG_ARCH_POPULATES_NODE_MAP . That is currently
i386, x86_64, powerpc, ppc and ia64. It does *not* align pgdat->node_start_pfn
but I don't believe that it is necessary.
I can't test it on ia64 until I get someone to restart the machine. The patch
compiles and is currently boot-testing on a range of other machines. I hope
to know within 5-6 hours if everything is ok.
