Kirill, As your mentions, there's not obvious wrong from the dmesg. Could you capture btmon log with raw data? (btmon -w xxx.log) In additional, did you build the last version of bluetooth-next? By my understanding, you can just duplicate the issue by the commit "044014ce85a1 Bluetooth: btrtl: Add Realtek devcoredump support"? Unfortunately, I can not duplicate this issue sofar.
