Comment 1 Scott Gayou 2018-07-20 19:39:13 UTC
Upstream workaround in gnome-bluetooth: https://gitlab.gnome.org/GNOME/gnome-bluetooth/commit/6b5086d42ea64d46277f3c93b43984f331d12f89

Note that the actual bug is not in gnome-bluetooth.

RHEL is not affected as RHEL-7 is running Gnome 3.26, which is not impacted.

Comment 2 Scott Gayou 2018-07-20 19:41:02 UTC
Created bluez tracking bugs for this issue:

Affects: fedora-all [bug 1606371]

Disable Bluetooth.

Comment 9 Scott Gayou 2018-08-09 18:14:10 UTC
It appears that a fix was merged upstream and may be available in a future release of BlueZ 5.51. gnome-bluetooth-3.28.2 will take advantage of this fix.
