Hi These messages appear on the kernel log when I am using BCSP: <3>bcsp_recv: Out-of-order packet arrived, got 1 expected 0 <3>bcsp_recv: Checksum failed: computed b237 received 0000 <4>Warning: kfree_skb passed an skb still on a list (from 000f77a4). <2>kernel BUG at skbuff.c:319! <3>bcsp_recv: Short BCSP packet Then the computer hangs. I enabled "Send CRC with every hci packet" in the kernel and in the bluetooth device. What's happening? Carlos AM Naxus Conectividad Móvil
