If you are using ext4, look for the "swapfile has holes
<https://bugzilla.kernel.org/show_bug.cgi?id=207585>" message.   There is a
kernel bug, but two proposed fixes, one looks like a quick hack, the other
points to a more basic flaw in the implementation.

One misconfiguration can cause multiple failures.

Other distros are reporting problems and have workarounds:

Maybe you shouldn't be using Fedora.   One reason Fedora exists is to catch
problems like this.  Given that there is a simple workaround and more than
one way to "fix" it, it may take some time for a fix to make it into the
kernel.
The bug was reported in May, so "some time" might translate to "real soon
now".

Why not  apply the workaround.
