I know that bug, Bluetooth has been messing with sleep since installing the 6.11 kernel on my Fedora 40 desktop. And I've seen many users reporting the same thing. My current solution is a script that disables BT on sleep
Never heard of this, but I just rebuilt my machine, which is still having issues with sleep. Seeing as how I have zero bluetooth devices (wires never fail me!), I will be disabling bluetooth immediately to see if this resolves my woes.
