Thanks.

It turns out that the other problem I was experiencing was a
manifestation of Debian bug #678696: the C600 driver takes a little
longer to enumerate the disks, and sometimes loses the race with the
initramfs init script.  The initramfs has no mechanism to attempt,
later, to activate the lvm vg.  So as a result the system failed to
boot some proportion of the time.  Adding a `rootdelay=' parameter to
the boot arguments worked around it, and the bug is fixed in Debian
jessie.

So these two machines are now working.  I have run them through the
usual set of commissioning flights and they are now in the test pool.

Thanks,
Ian.
