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).

I'm not aware of anything that is trying to use NBD - I did experiment a bit a while back, but didn't get anywhere. I thought xen might be using it behind the scenes in some way.

Xen doesn't use nbd.  I bet you have something in
/etc/rc.d/init.d that is starting nbd.
