I've seen a lot of reports about this issue. Unfortunately this was only reproducible with specific MicroSD cards.
Are you able to reproduce this issue with multiple MicroSDs? What type of MicroSD produce this issue?
From the Bug: # that does not matter, the important part is that it works with Raspbian # while it does not with Fedora.
it does matter, because there is zero free documentation about the sdhost controller on the BCM2835. So everything depends on helpful users and a lots of testing. Raspbian uses their downstream sdhost driver bcm2835-sdhost, while Fedora the mainline driver bcm2835. This one was derived from the downstream one around kernel 4.12. Thanks for letting me know it's a Kingston card. I've a few Kingston cards and never had a problem. So i wouldn't think there is a general issue with them.

I see nowhere on this list mentioned this problem, really nobody is using MicroSD directly?
I primarily use mSD cards directly, I currently have 12 RPi of different models from the RPi2, original 3 (a couple of gens), the 3B+, 3A+ and even a CM3 based device running various Fedora images on both aarch64 and ARMv7 with no issues.
One should also use more wide range of MicroSD cards.
From the Bug: # I have verified now that it is a regression # since (as this kernel boots fine directly from my Kingston MicroSD): # Fedora-Server-29-1.2.aarch64.raw.xz = kernel-4.18.16-300.fc29.aarch64
Thanks this is very helpful. Could you please test Fedora kernel 4.19 and 5.0 for aarch64? This would narrow down the issue much more.
Also it's possible under powered PSUs might cause something like this, I've had reports of issues with SD cards that have gone away with different PSUs, what is the rating of your PSU?
From the Bug: # Original Raspberry PSU 2.5A
I don't think this is power related.
Thanks Stefan
