Instead of using LABEL=xx, specify disk with /dev/disk/by-label/xx
For UUID=xx it is /dev/disk/by-uuid/xx
This works great and it solves my reported problem, so this bug report may be invalid now.
However since /etc/fstab supports specifying disks by LABEL=xx or UUID=xx and various howto show this method, I think that this should still be supported.
Upstream suggested a working work-around:
