This problem affects me as well, and this workaround worked for me.

The message I get at bootup says that /dev/mapper/system-usr does not
exist. Let me know if more detail would help, and I can try to break it
again and note down specifics. However, my USB keyboard doesn't seem to
function in the shell I get dropped into, so I currently have limited
diagnostic capabilities when the problem occurs.

As far as I can tell, the problem only occurs with
linux-image-3.16-2-amd64, not with linux-image-3.16-1-amd64.

I have a fairly large /etc/fstab, but here is my 'system' VG:

------------------------- 8< -------------------------
# awk '/^\/dev\/mapper\/system-/ {print $1"\t"$2}' /etc/fstab
/dev/mapper/system-root       /
/dev/mapper/system-ssddata    /ssd
/dev/mapper/system-opt        /opt
/dev/mapper/system-usr        /usr
/dev/mapper/system-usr.local  /usr/local
/dev/mapper/system-var        /var
/dev/mapper/system-swap       none
------------------------- >8 -------------------------

No RAID of any sort, no dm-crypt. The LVM PG is directly on an MBR
partition on a SATA SSD.

I'm happy to provide any further information required, or even work on
a patch when I get time.

Thanks,
Steven.
