Problems with amdgpu and hibernation from kernel 6.17.0

Hello to everyone,
since kernel version 6.17.0, I'm having problems with hibernation on my 
desktop system, while everything works fine on my laptops.

The problem is that after starting hibernation (either using KDE logout screen 
or by writing "disk" on /sys/power/state), the screen goes black but the 
system doesn't actually shut down and I need to press the reset button to 
restart the system. I tried leaving it alone for half an hour, but the 
situation didn't change.

I tried debugging the issue according to https://www.kernel.org/doc/html/
latest/power/basic-pm-debugging.html and I found out that the problem seems to 
be caused by the amdgpu module (or by one of the modules it requires), which I 
need for my Radeon AMD Radeon RX 6700 XT video card.

Just to be on the safe side, I tried switching from gentoo-kernel with custom 
configuration to gentoo-kernel-bin, but unfortunately nothing changed.

I tried searching the web for similar issues, but I found nothing. Has anyone 
experienced this kind of problem? If so, were you able to solve it? Is there a 
way to get more information about what is happening?

Tbanks in advance

Stefano
