https://bugzilla.kernel.org/show_bug.cgi?id=204275 Bug ID: 204275 Summary: bluetoothd consumes 100% cpu on keyboard disconnect Product: Drivers Version: 2.5 Kernel Version: 3.x + Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: steve@xxxxxxxxxxxxxxx Regression: No Many bluetooth HID keyboard profile devices disconnect on idle to save power, I have two such devices: Logitech Y-X5A77 keyboard Sony PS3 bluetooth remote control When the device disconnects on idle the g_io_channels get disconnected bluetoothd[3167]: profiles/input/device.c:ctrl_watch_cb() Device 00:07:61:F6:C9:7D disconnected bluetoothd[3167]: profiles/input/device.c:intr_watch_cb() Device 00:07:61:F6:C9:7D disconnected But, something isn't closed properly (possibly g_io_add_watch) since bluetoothd then spins at 100% CPU in g_main_loop_run() until the device reconnects, at which point every works normally again until the device next idles.
