That's quite likely indeed.
This said, I've had such UUID problems in the early boot (initramfs) that
involved the swap partition rather than the root partition because the
code that tries to resume from hibernation looks for some tell-tale sign
in the resume partition (usually also playing the role of the swap
partition), and this is done before trying to mount the root partition.
IIRC booting with `resume=no` on the kernel's command line worked around
the problem in my case.
