You did have a kernel update.

You must have been upgrading this system for quite a while.  The debug
kernel modules got accidentally pulled in back then.  You can do "dnf
remove kernel-debug*" to get rid of those.

I have no idea why hibernate stopped working, but it seems to not like
something the BIOS is doing.

Dell systems recently got BIOS updates.  My newest Dell system did a 2-step BIOS firmware
update dance.  The updates are dated May 22.

" - Firmware updates to address security vulnerabilities including (Common Vulnerabilities
and Exposures - CVE) such as CVE-2022-0004, CVE-2022-0005, CVE-2022-21123,
CVE-2022-21125, CVE-2022-21127, CVE-2022-21151, CVE-2022-21166, and CVE-2022-21181"
  
These might have introduced something in the BIOS that kernels "don't like".   I see a bunch of
driver firmware updates around the same time.   If these are problematic there may be reports for
for other distros.
