Booting F40 kernel 6.8.10 hangs on Dell Inspriron 15 5510

It looks like your boot process is waiting for a partition with some UUID, but it’s not appearing. I had the same issue. It turns out the UUID for my swap partition didn’t match the UUID on the kernel command line after “resume=”. For whatever reason, kernel 6.8.9 was fine with it, but 6.8.10 wasn’t. There are several places for the swap UUID: the swap partition itself, /etc/fstab, /etc/default/grub, /etc/kernel/cmdline and /boot/grub2/grub.cfg. Make all those files use the same UUID.
