Public bug reported:
After upgrading from Ubuntu 18.10 to 19.04 my BTRFS Raid0 based system
doesn't boot anymore.
It drops to busybox because of an error mounting the root file system.
Manually trying to mount root reveals an error message saying that the
second raid volume could not be found by UUID. But the output from
`blkid` shows that the volume with the UUID in question exists.
Booting the system using the previous kernel 4.18 from advanced boot
options works flawlessly.
