Hello everyone,
today I noticed that when connecting to my phones wifi hotspot, systemd-resolved will take up too 100% CPU usage.
Additionally firefox and skype crash.
Furthermore I can't resolve any domains.
This is the status of systemd-resolved.service:
Dez 06 21:59:15 S2000 systemd-resolved[644]: Using degraded feature set TCP instead of UDP for DNS server 192.168.208.87.

This is the status of systemd-resolved when connecting to my routers wifi. This will work as usual:
Dez 06 22:00:58 S2000 systemd-resolved[644]: Using degraded feature set UDP instead of UDP+EDNS0 for DNS server 10.5.48.1.
Dez 06 22:15:58 S2000 systemd-resolved[644]: Grace period over, resuming full feature set (UDP+EDNS0) for DNS server 10.5.48.1.
Dez 06 22:15:58 S2000 systemd-resolved[644]: Using degraded feature set UDP instead of UDP+EDNS0 for DNS server 10.5.48.1.
I am also using DNSCrypt if that is of any help.
I can re-produce this problem at any time. So please let me know if there are any logs that I can provider to help solving this issue/bug.
Thanks!

Well I fixed it for now simply by stopping and disabling systemd-resolved.service

Same problem, a bit annoying. Seems this is related to systemd v247 #17870 issue [1]. It is fixed now, so waiting for the package update.
