I made the last update to Tumbleweed snapshot 20201212 the last weekend. Today I got a system crash. After restarting, the sound is reproduced with noise and distortion. I made a "lsmod", and surprisingly I see: ecdh_generic 16384 1 bluetooth rfkill 28672 5 bluetooth ecc 36864 1 ecdh_generic But my computer has no Bluetooth devices! After blacklisting the modules bluetooth, ecdh_generic and bnep, and restarting, the system works fine again.
