Hi Andrew,

My new most likely culprit is one of my own changesets, 19268. Can you try:
 hg export 19268 | patch -Rp1
Please? You'll have to hit return on a few patch warnings -- they are
failures in ia64-specific code so they are harmless to ignore. Again, then
build and install only the hypervisor binary itself.
