Thanks for the debug patch. I have attached the collected information.

from your full log that it looks like the bug is happening shortly
after we start userspace.  So it may be differences in my userspace
set up that meant I haven't been able to reproduce it.  I'll have
another look at that when I get a chance.

Let me know if you need access to the system on which i can recreate the
bug. I can make that system available for you to debug this issue.

That's probably a good idea.  I'm still pretty baffled by this, so it
will probably take several more rounds of debug patches to start
getting a handle on it.
