No. It's above me.

2.6.27 xen-ified kernel & Xen Unstable ( the most recent). Attempt to
shutdown and start it again gives VBD cannot be connected . Hotplug scripts not
working. That's a core issue, same behavior as under 2.6.29-rc7 (with XSAVE
patch ). Kernel doesn't seem to be a root cause.

Could you try bisecting xen-unstable to see which change started failing for
you? There were some recent changes to the hotplug scripts which could have
introduced a problem.

However, I'm pretty sure I started seeing this problem without updating my
usermode tools, so there could also be a kernel problem. But its not obvious
what it might be.

Thanks,
