Public bug reported:
It could be a problem with the network, but I'm seeing cups-browsed
appearing to keep one CPU core busy. According to systemctl, it has used
51 minutes of CPU time since being started 6 hours ago (the laptop has
been suspended a few times in that time):

It may be unrelated, but I'm also seeing warnings like the following in

that cups-browsed is losing track of an idle or timeout function.
