Hi all, I noticed that bluetoothd was jumping to 100% cpu usage when I
switch my bluetooth keyboard off. Then when I turn it back on the CPU
drops back down.
Details:
Ubuntu 14.04 32bit
bluetoothd 4.101
default kernel 3.13, bluetooth module 2.17
I upgraded to bluetoothd 5.19 and it does the same thing.
here is a backtrace from gdb (bluetoothd 5.19):
#0 0x00007ffff71a8fa0 in __poll_nocancel () at
