Public bug reported:
Currently running Kubuntu 18.10, Dell XPS 13 9350
Since updating from Kubuntu 18.04 to 18.10, the avahi-daemon has been
consistently hampering network performance and using CPU for long
periods of time.
When booting machine from off state, avahi-daemon uses an entire CPU at
max load for approx 10 minutes. During this time, internet connectivity
via wifi is essentially unusable. The wifi connection is good, but it
seems that http transactions are cutoff mid-way so no webpage is able to
load.
When waking from sleep, the avahi-daemon causes similar symptoms, but
with less than 1 full cpu usage, and with somewhat less degraded network
performance, but still quite unusable.
I have never had issues with avahi prior to the 18.10 upgrade, so I am
fairly confident the issue is rooted in that change.
