Comment 2 Chris Murphy 2016-09-07 16:03:29 UTC
Not a new bug, goes back to at least kernel 4.4.14, but only causes gnome-shell notification using debug kernels.

Comment 3 Chris Murphy 2016-09-07 16:07:27 UTC
I wonder if this is a kernel bug that could result in intermittant bluetooth mouse problems? I've got a long standing problem where the mouse inexplicably disconnects maybe half dozen times a day. Bug 1368246.

Comment 4 Chris Murphy 2016-09-13 16:21:35 UTC
Does it make sense for me to file this upstream and if so against what component? It's apparently tainting the kernel so it kinda makes subsequent events less useful.

Comment 5 Laura Abbott 2018-04-06 18:14:48 UTC
I think this has been fixed?
