Unless you were using 0.6.3 or older, I would have expected that xenvbd
wouldn't touch the boot disks without xenhide. Is it possible that the damage

That's an 'assert' statement being executed, eg in one of the drivers there is
a statement that says 'if this condition isn't true then crash'. Can you tell

Ah yes, xenhide 0.6.4 didn't do the right thing with Xen 3.2.0.
