Bug report

Describe your environment

Describe the problem

Steps to reproduce:

  1. Install ivpn through apt and log in

Observed Results:

Installing the IVPN package on Ubuntu 22.04 LTS on devices using iwlwifi causes frequent crashes, seen in dmesg output. These occur whether or not the firewall is enabled. I have observed this on an XPS13 9310 and also on Framework Laptop 13 13th gen.

These crashes cause WiFi connectivity to fail entirely for a few seconds at random times around every 2-3 minutes.

This archlinux thread shows someone else also identifying IVPN as the source of the same problem, on quite a different setup.

Expected Results:

That iwlwifi would not crash. If I uninstall ivpn these crashes do not occur.
