Seems to be specific to some AMD models. I’m running it on a ~ten year old Asus. Timeout waiting for tpm as seen in someone else’s post at https://discussion.fedoraproject.org/t/much-longer-boot-time-after-updating-to-fedora-41/132603/15
Problem only occurred after upgrading from 40 to 41 - can be seen by pressing Esc while it’s booting.
Probably only affects a small number of AMD machines.
