Description of problem: My laptop had one CPU spinning at 100%. I killed the process with SIGABRT and this is the backtrace: (gdb) bt full #0 0x0000561a14675f73 in find_service_with_state (list=0x561a15b68010 = {...}, state=BTD_SERVICE_STATE_CONNECTED) at src/device.c:346 service = 0x561a15b5c9e0 l = 0x561a15b654d0 = {0x561a15b5c9e0, 0x561a15b5ca20, 0x561a15b80900} #1 btd_device_is_connected (dev=<optimized out>) at src/device.c:3279 No locals. #2 btd_device_is_connected (dev=0x561a15b69390) at src/device.c:3274 No locals. #3 adapter_remove_connection (adapter=0x561a15b55c20, device=0x561a15b69390, bdaddr_type=0 '\000') at src/adapter.c:7489 remove_device = <optimized out> __btd_debug_desc = {file = 0x561a146da072 "src/adapter.c", flags = 0} __func__ = "adapter_remove_connection" __btd_debug_desc = {file = 0x561a146da072 "src/adapter.c", flags = 0} #4 0x0000561a146632ad in adapter_stop (adapter=0x561a15b55c20) at src/adapter.c:7525 device = 0x561a15b69390 addr_type = 1 '\001' __func__ = <optimized out> __btd_debug_desc = <optimized out> #5 settings_changed (adapter=0x561a15b55c20, settings=<optimized out>) at src/adapter.c:622 changed_mask = 1 changed_mask = <optimized out> __func__ = <optimized out> __btd_debug_desc = <optimized out> __btd_debug_desc = <optimized out> #6 new_settings_callback (index=<optimized out>, length=<optimized out>, param=<optimized out>, user_data=0x561a15b55c20) at src/adapter.c:705 adapter = 0x561a15b55c20 settings = <optimized out> __btd_debug_desc = {file = 0x561a146da072 "src/adapter.c", flags = 0} __func__ = "new_settings_callback" #7 0x0000561a146a35a9 in queue_foreach (queue=0x561a15b4f680, function=0x561a1469bcd0 <notify_handler>, user_data=0x7ffd4092c850) at src/shared/queue.c:207 next = 0x561a15b62f60 entry = <optimized out> #8 queue_foreach (queue=0x561a15b4f680, function=0x561a1469bcd0 <notify_handler>, user_data=0x7ffd4092c850) at src/shared/queue.c:190 entry = <optimized out> next = <optimized out> #9 process_notify (mgmt=0x561a15b4f330, event=<optimized out>, index=<optimized out>, length=<optimized out>, param=<optimized out>) at src/shared/mgmt.c:349 match = {event = 6, index = 0, length = 4, param = 0x561a15b4f3b6} match = <optimized out> #10 can_read_data (io=<optimized out>, user_data=0x561a15b4f330) at src/shared/mgmt.c:409 mgmt = 0x561a15b4f330 hdr = <optimized out> cc = <optimized out> cs = <optimized out> bytes_read = <optimized out> opcode = <optimized out> event = <optimized out> index = <optimized out> length = <optimized out> __func__ = "can_read_data" #11 0x0000561a146c56d9 in watch_callback (channel=<optimized out>, cond=<optimized out>, user_data=<optimized out>) at src/shared/io-glib.c:157 watch = <optimized out> result = <optimized out> destroy = <optimized out> #12 0x00007f3bdb01a26c in g_main_dispatch (context=0x561a15b49df0) at ../glib/gmain.c:3344 dispatch = 0x7f3bdb077be0 <g_io_unix_dispatch> prev_source = 0x0 begin_time_nsec = 649780860485399 was_in_call = 0 user_data = 0x561a15b4f6b0 callback = 0x561a146c56b0 <watch_callback> cb_funcs = 0x7f3bdb109280 <g_source_callback_funcs> cb_data = 0x561a15b4f760 need_destroy = <optimized out> source = 0x561a15b4f6e0 current = 0x561a15b55950 i = <optimized out> __func__ = <optimized out> #13 g_main_context_dispatch_unlocked (context=0x561a15b49df0) at ../glib/gmain.c:4152 No locals. #14 0x00007f3bdb07b2a8 in g_main_context_iterate_unlocked.isra.0 (context=0x561a15b49df0, block=block@entry=1, dispatch=dispatch@entry=1, self=<optimized out>) at ../glib/gmain.c:4217 max_priority = 200 timeout = 0 some_ready = 1 nfds = 32 allocated_nfds = <optimized out> fds = 0x561a15b7dc20 begin_time_nsec = 649780860418833 #15 0x00007f3bdb020227 in g_main_loop_run (loop=0x561a15b49fe0) at ../glib/gmain.c:4419 self = <optimized out> __func__ = "g_main_loop_run" #16 0x0000561a145faddd in mainloop_run () at src/shared/mainloop-glib.c:66 No locals. #17 mainloop_run_with_signal (func=0x561a1464e3e0 <signal_callback>, user_data=0x0) at src/shared/mainloop-notify.c:188 data = 0x561a15b55820 io = 0x561a15b55840 ret = <optimized out> data = <optimized out> io = <optimized out> ret = <optimized out> __n = <optimized out> __s = <optimized out> __p = <optimized out> #18 main (argc=<optimized out>, argv=<optimized out>) at src/main.c:1452 context = <optimized out> err = 0x0 sdp_mtu = 0 sdp_flags = <optimized out> gdbus_flags = <optimized out> __func__ = "main" __btd_debug_desc = {file = 0x561a146dcbd4 "src/main.c", flags = 0} Version-Release number of selected component (if applicable): bluez-5.73-2.fc40.x86_64 How reproducible: So far only happened once.

I *think* this looks like https://github.com/bluez/bluez/issues/785 , right? If so, 5.75 should fix it. I'm gonna mark the 5.75 update as fixing this, please comment if you think that's wrong.

It does look similar, though in my case it was caused (I think) by trying to stop the service, not an rfkill block. I've had it happen a few times since filing the bug, so I'll just keep an eye out after the update. Thanks!
