Greetings. On Monday I installed the stable GuixSD on my newly acquired Lenovo X200 with an Atheros Wi-Fi (ath9 driver). It worked like a charm, so I decided to install the unstable variant.
Yesterday I lost half a day fighting to install and understand the development release. The overall feeling of this particular issue is that the kernel chokes on any significant Wi-Fi traffic and remains under pressure even when I use the hardware switch to reload the wireless card. Today, I connect to the internet through an USB cable from my phone. The wireless is disabled. System stability is perfect. Could I ask for a configuration snippet which deploys an earlier version of the kernel? This is my first serious attempt to learn Guix and the documentation is unhelpful in this regard. Thank You
