I see this error, too

Same here on regular F30 Workstation. FAT dirty bit is still set after reboot:

~  sudo fsck /boot/efi
[sudo] password for exalm: 
fsck from util-linux 2.33.2
fsck.fat 4.1 (2017-01-24)
0x25: Dirty bit is set. Fs was not properly unmounted and some data may be corrupt.
1) Remove dirty bit
2) No action

/dev/nvme0n1p1: 32 files, 4623/51145 clusters
 ~ 

However, it doesn’t help.

I’m also seeing this (including the dirty bit reported by exalm) on a regular F30 workstation following a clean install on a Dell XPS 9370 machine. This is also using an nvme drive. The error message flashes up then disappears and the machine boots as normal and everything is otherwise fine.

I’m not seeing this on another machine with /dev/sd_ drive so wonder if it’s nvme specific?

i think that was caused by dbus-broker (or some systemd)? i had it both on Fedora30 and Silverblue 30, but it is now fixed

I don’t see how dbus-broken can possibly cause it, but whatever, still happening here.

The same issue: 1699761 – 'error: ../../grub-core/fs/fat.c:447:not a FAT filesystem' displayed briefly during boot

yeah, i dont see either how is connected w dbus-broker, but it was the package that updated and fixed it; it could be some scriptlet that runs and causes the error; i might be wrong, but since i haven’t the error anymore i cant investigate what was exactly wrong …but for issue to be corrected you also need to fix the dirty bit

I have the same problem after clean install F30 Beta.

I suspect it may be an F30 anaconda installer issue, b/c the grub error does not appear when upgrading F29 → F30.

Same partition scheme in both cases

More than likely had to do with the new grub entry created fixing it.

I noticed the same issue and I have plain old SSD.
