If your system does not boot anymore please check if you have the required GPU firmware installed. In F37
linux-firmware won't include the (sizeable) GPU firmware anymore which was moved to vendor-specific packages (e.g.
amd-gpu-firmware). For some reason this change was pushed to F36 with
$ rpm -q --recommends linux-firmware amd-gpu-firmware intel-gpu-firmware nvidia-gpu-firmware
So if you have
install_weak_deps=False in your
/etc/dnf/dnf.conf this means you won't have these packages by default and your system won't boot anymore.
You can fix this by installing the GPU firmware manually, e.g.:
sudo dnf install amd-gpu-firmware
See bug 2125536 for more information.
(Installing the GPU firmware won't fix the AMD audio issues though)
libheif is not part of Fedora (likely installed from
rpmfusion-free) and the update was not coordinated between Fedora + RPM Fusion (as expected - RPM Fusion is an independent 3rd party repo. I think there is some progress to rebuild the package but you should watch RPMFusion bug 6158.
Therefore you should not give negative karma to this update.
@tomato: I don't think this is planned for the EPEL exim package (please note I'm just a random Fedora contributor, not an Exim packager) but it should be pretty easy for you to create a COPR repo for yourself. I'm currently swamped with work so I can't offer this as a volunteer for free.
