Comment 6 for bug 1581761

After multiple update-initramfs and kernel reinstalls instead of message 'fstype not found' I have 'can't open /dev/mapper/ubuntu-root no such file'. However all the rest of the stacktrace seems to be similar as already attached photo of the stacktrace. I check if I have installed lvm2 and it is. Installed 3.16.x kernel (or 3.19.x) and situation didn't changed.
