Status icons relating to kill-switches froze, terminal reboot command lagged, then reboot froze before shutdown with only one line of "^@"s across the top of the screen, after which I just removed the battery. Any known bugs that could have caused this?
Sadly i not a Guru yet to know whats going on in your device, however we are lucky to have one @guru here so may helping you. However i did a massive troubleshooting and researching yesterday on my L5 and i confident to tell you that the Librem 5 work really fancy even under Gnu Byzantium.

What does this expresion mean in Spanish
You do not speak Spanish? as far i know you do
I do but I don‘t know “yay …”
It’s an interjection in English, meaning hooray!, hurrah!, great!, awesome!, nice!, sweet!, etc.: yay - Wiktionary, the free dictionary
I.e. it’s English and not following el DRAE ( Diccionario de la lengua española de la Real Academia Española)
