FTLIW, my own primary desktop has an AMD graphics card (and has since before the initial Debian install), and doesn't have these large initrds: $ lh /boot/initrd.img-* -rw-r--r-- 1 root root 36M Sep 2 08:27 /boot/initrd.img-5.18.0-4-amd64 -rw-r--r-- 1 root root 36M Dec 9 07:53 /boot/initrd.img-6.0.0-4-amd64 I haven't dug into them any deeper than this, but it may be worth having the confirmation that it's not something common to all machines with AMD graphics cards. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
