После update-initramfs (MODULES=most) на свежеустановленном Debian Stretch после загрузки не работает WiFi (iwlwifi). Обновлял initramfs после изменений в crypttab (переименования устройства), система установлена на LVM on LUKS. WiFi без проблем заводится после
rmmod iwlmvm iwlwifi && modprobe iwlwifi
