Hi-
I have no useful advice about filesystem recovery, but would like to
point out that newer kernels are backported to Ubuntu LTS versions and
can be installed without any significant disruption of the system.
The normal kernel backports are named 'linux-generic-lts-<version
codename>', and the low latency versions are
'linux-lowlatency-lts-<version codename>', so you could install kernel
3.16 (from 14.10 "utopic") by installing linux-lowlatency-lts-utopic,
and kernel 3.19 (from 15.04 "vivid") by installing
linux-lowlatency-lts-vivid. Kernel 4.1 will be available as
linux-{generic,lowlatency}-lts-wily a bit after 15.10 is released.
