There seems to be some difference in Pi's, we tested the Fedora 34 and 35 images on various Raspberry Pi 4's - 2GB, 4GB and 8GB. The only board which required the firmware provided dtb was the Raspberry Pi 400. From the bug, someone else hit it with the Raspberry Pi 4 8GB, but I was unable to reproduce. We compared the eeprom bootloader versions, and both were running the same version (c2f8c388 - Apr 29 2021).
Have you tried a different mSD card?
Hmm, I picked up a Pi4 4G recently, and was also unable to boot Fedora from the SD card (had to use a USB adapter instead). Same error as in this thread, tried multiple cards (including a card from a Pi3), no different.
