I was initially hoping that it was simply a version issue, but when I compiled and booted 6.6.9, with the same iwlwifi driver version that I had before, Bluetooth was still not working (the dmesg for that boot was attached to the original email). So I was hoping that there's maybe some microcode or other persistent state or such that may explain why the Bluetooth suddenly disappeared, as the only other option that I can think of, would be sudden hardware failure (not sure if that happens, I haven't heard of that with integrated chips). Thanks again for your reply, I appreciate it! Ramses
