Background: I was changing the firewall zone in the settings of my WLAN
connection using NetworkManager. Suddenly I noticed many web sites were
becoming unreachable and commands such as "ss -na4" would hang indefinitely
(Ctrl-C wouldn't work). The processes of commands that involved the network
could not be killed, not even with SIGKILL.
It might also be worth mentioning that a VirtualBox VM was running at the time,
again running Tumbleweed and NetworkManager. The VM had a network interface
bridged to the wlan interface, wlp3s0.
It was not possible to shut down or even kill the VM when the issue was
noticed. Shutting down the actual machine wasn't possible either, a hard
poweroff had to be done.
The output of dmesg follows below, with a few lines before the "cut here" mark
for context:
