Cannot suspend computer / AMD dGPU does not work after kernel update (6.7.5)

In order to ensure that your kernel 6.7.4 does not get deleted (usually, Fedora keeps only the recent 3 kernels), you should adjust the related config file and increase the numbers of kernels that are to be kept. Please read from this post to find out how to do that:

By default, Fedora keeps only the most recent 3 kernels. If that issue happens, I suggest to change (in advance to the dnf command) the option installonly_limit=3 to installonly_limit=4 in /etc/dnf/dnf.conf, which increases the number of kernels that remain installed to 4.

I suggest to do this immediately and always keep the number sufficiently high to keep 6.7.4 installed. Once a new kernel solves your issue, you can reduce the number back to 3, which then will at the next update remove the old kernels at once.

This is not entirely true. Yes, Fedora keeps 3 kernels on the system by default, but one of those is the running kernel that you have when doing the update. This specifically keeps it from removing a known good kernel. So assuming you have 6.7.4, 6.7.5, and 6.7.6 installed, but you stay booted into 6.7.4 because the other 2 are broken, when you update to install 6.7.7 it will remove 6.7.5
