A further point - I mentioned in my last mail that attempts to access an
nbd device start very early in the boot sequence. I now also notice
after looking at several boot sequences that the first seems always to
be an attempt to access nbd60, sector 0 (but the sector 0 may be a red
herring). I suspect something is trying to acccess block device 43,60
hoping to find something other than a non-existent nbd device).
