OK, I have downdated the kernel, run grub2-mkconfig so we should be
back on the same plane as before. So how do I debug this? Thanks!

An important thing to note is that the resume=/dev/sda? parameter that
I had installed previously to get my system to come back from
hibernation is not updated with grub2-mkconfig. So fixing this feature
is also very important.

Many thanks again!
