I’m on the 31 Beta and have been running kernel 5.3.5-300 for several days without problems.
This morning, I ran “dnf upgrade --refresh” and it upgraded my kernel backward to 5.3.4-300. When the system rebooted, 5.3.5-300 was still at the top of the grub list, but 5.3.4-300 was pre-selected and that is what ran without manual intervention.
This all seems very strange. Any ideas?
