On December 24th, 2024, Debian had me a gift for me: it installed Linux kernel 6.11.10, and suddenly the WiFi module of my laptop stopped working. I quickly found a workaround (selecting an older kernel with GRUB during boot) and hoped that the problem would be fixed by the next kernel update or by a firmware update from my laptop’s manufacturer. Sadly, kernel 6.12 arrived and nothing changed. I finally took some time to really investigate the issue.
