I tested the v3.19.8-ckt15-vivid kernel and also the 3.19.0-49 kernel.
Both of them seemed to boot, but there were graphical glitches and I
could not read or do anything.

Title:
Kernel panic - not syncing: VFS: Unable to mount root fs
Status in linux package in Ubuntu:
Confirmed
Bug description:
I'm getting a kernel panic when i try with the standard kernel for Ubuntu
14.04.4 LTS: 3.19.0-26.
It says "Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)"
I also use btrfs on the root partition (this may be relevant).
I attached a photo of the kernel panic screen.
When i boot into an older kernel (3.13.0-77-generic) everything works.
Currently I'm on linux-generic-lts-wily (4.2.0-27-generic), because that one
also works.
I made this bug report with the older kernel, so the kernel-version
from the automatic debug-information is wrong.
