Kernel 5.12.12-300 breaks host resolution
https://bugzilla.redhat.com/show_bug.cgi?id=1976371
Very weird that the kernel could break name resolution since that
all works at library level. Maybe some "deprecated" interface
is being used by 99% of the lookup code, and they got rid of
it completely in the new kernel?
I had name resolution break on one of my F34 computers after the latest
kernel update. Restarting systemd-resolved fixed the problem. I
rebooted and the same thing happened: no DNS until systemd-resolved
was restarted.
None of systemctl status, dmesg, or journalclt showed anything
suspicious or interesting.
My other Fedora computers are fine. I suspect the difference is that
the problem computer is using bridged networking instead of a direct
ethernet connection. Perhaps a timing issue with the bridge?

Hi Jim,
My only computer with the issue is also using bridge
networking.
Eyal recommendation to alter nsswitch.conf
# hosts: files myhostname mdns4_minimal [NOTFOUND=return] resolve
[!UNAVAIL=return] dns
hosts: files myhostname mdns4_minimal [NOTFOUND=return] resolve dns
worked for me.
