So f2654… is actually just RELEASE-4.16.1. :-) I think the issue is that
you’re trying to do a bisect across different branches. What you need to do is
to find the point where RELEASE-4.16.1 and master diverged; you can do that
with `git merge-base`:
$ git merge-base RELEASE-4.16.1 master
Verify that things work properly at *that* commit, then use that as the “good”
starting point.
Unfortunately I’m not really doing Xen development anymore, so I can’t help dig
into the logs or try to repro the issue. (One of the unusual thing you’re
doing, it seems, is to boot with *only* a cd-rom drive, and no ’normal’ drives,
or even any network cards.). I’ll try to get someone else to take a look at
this thread.
