[Galaxy S III Original Android Development] Klaerchen:
(1) Interesting, that pairing works on your devices!

(2) The build consists only of the LineageOS repositories without foreign components, i.e. standard kernel. Our devices comes with pegasusq governor which is a hotplugging governor as far as I know.

(3) Could it be, that a warm-reboot of Android does not do a kernel-reboot? Then the last_kmesg dates from my previous reboot to start with a clean environment. Not from the Bluetooth-initiated warm reboot.

(4) The following are the last before Android died:

especially the line:

E BufferQueueProducer: [com.android.settings/com.android.settings.Settings$BluetoothSettingsActivity] dequeueBuffer: BufferQueue has been abandoned

shows, that the Bluetooth settings app is part of the problem.
