All it takes is one systemd bug, or any number of other conditions
that prevent a proper umount.
I have seen various kernel bugs cause it, I have seen the hw operating
the disks stop working.
In general using ext4+journal and/or xfs under the exact wrong
conditions can result in an unbootable sys

Of course you could boot to the previous kernel, remove the latest one, reboot
again to the previous
kernel and allow the upgrade to test.

Ok, I think I've finally managed to remove the journal on /boot. I did
it by rebooting into an old F30 boot media in troubleshooting mode using
'tune2fs -O ^has_journal'. I was unable to do this on the disk even in
single user mode, as it always marked the /boot partition as unclean,
and alway

Did you do a lazy unmount? Any other umount will fail if there are
open files, and lazy does not actually unmount it until whatever has
the files open closes them, which generally means it never gets
unmounted.

I like the idea of just removing the journal tag, but I don't think that
I can modify the /boot filesystem. Doing a umount works, but tune2fs
claims that an e2fsck is required. Running e2fsck says that the
filesystem is still mounted, even though it is not. Doing a fuser

You have to hit the timing right. ie install the kernel package and
as quickly as possible reboot (automated, or very efficient).
And if the update is more than just kernel, that may slowdown the
process enough that the immediate reboot won't be quick enough.
I have seen it 3-5 times and that is

A sync will flush the writes to the journal were the data is safe. It
will not force a replay of the journal.
Nothing except removing the journal from the ext4 filesystem will fix it.
This is not a fedora bug, this is a long standing

Interesting! This machine does reboot in about 5secs and the other
machines take longer, so it makes sense. My /boot is mounted just like
/home and / as follows:
/dev/sda1 on /boot type ext4 (rw,relatime,seclabel)
I assume that a symple sync would flush the journal. Its pretty easy to
