I'll narrow it down, but it will take a while. I'll let you know.

As a starting point, if you are also using up-to-date linux-2.6.18-xen.hg then try reverting it back a month and see if the problem goes away. If not, bring back to tip and try same on xen-unstable.hg. This will establish which repo contains the bug. It’ll probably turn out to be xen-unstable.hg, at which point I would do ‘hg –v history xen | less’ to look for scary looking patches inside the hypervisor itself, and use that to guide which changesets I test for working vs non-working. You should be able to do much better than a binary chop this way.
