Hi. It pains to say that I'm currently remote from my qnap machines, and
also, because of a lack of a (serial) console I am extremely wary of
fiddling with boot scripts on these machines, since they are doing useful
work and holding useful data. I wish I could be of more help, but sadly I
don't have a spare machine for debugging work.

(And sorry for just using a one-off email address, but posts to the 
Debian bugtracker seems to be an incredibly strong magnet for spammers 
and email harvesters)

Thanks again for your time and your work. :) 

For anyone testing, I can say that the problem happens only occasionally. I
think once out of the ~4 reboots I have performed so far.
