I'm not entirely sure what difference I made, but it seems that this
problem has disappeared (hasn't surfaced over the last three days,
whereas before it was a matter of hours).
I've updated the kernel to statically contain bcache and the DM/md
infrastructure (which should be unrelated, except for being part of a
stack of block devices). Anyway, that seems to have done the trick, in
case anybody else is experiencing this.
