The default systemd-boot installed kernels on fedora end up in the form:

My Fedora goes with grub, the kernel path is below via grubby --info
ALL|grep kernel (strip useless info):
kernel="/boot/cffa62f902ee423bafa9f42e6ab99f3c/6.2.13-300.fc38.x86_64/linux"

I got an early error in /usr/lib/kdump/kdump-lib.sh:
"Failed to detect kdump kernel location"
It seems prepare_kdump_kernel() assumes the kernel file name is
"vmlinuz", so not sure why your "linux" kernel works.
Long time not reading the code, there seems prepare_kdump_kernel() in
the lib script use a different way to get the kernel path.
Where the kernel version is a directory containing the kernel (linux)
and the initrd. Thus _find_kernel_path_by release needs to be a bit less
strict and allow some futher characters on the grubby (really bootctl)
output.
