Firstly, I can't test any upstream kernel. Secondly, I didn't say that it happens all the time.
Please, read the large number of similar observations. After removing resp. changing to the correct UUID, everything seems to work okay for subsequent generations of the initramfs. Also, look at the various dates, it seems to occur at times, and has occurred throughout a longer period, that initramfs through some seemingly unknown mechanism selects a non-existing UUID for resume. Therefore I considered it worthwhile to report this bug, since it happened to me during the recent upgrade to ubuntu 18.04. It might happen to more users, and it not useful to close with 'worksforme'. Because 'worksforme' in 99% of the cases, and even if not reproduceable, means a certain probability of occurrence. And as long as nobody knows why this happens, something ought to be done.
