I think that's what was happening on https://bugzilla.kernel.org/show_bug.cgi?id=207169 Without rfkill (directly entering suspend), the issue seemed to disappear: https://bugzilla.kernel.org/show_bug.cgi?id=207169#c14 The bluetooth commits you've identified added a suspend hook in bluetooth so it gracefully disconnects active connections and sets up wakeup hooks on reconnections. If Bluetooth is rfkill-ed, it won't be able to do this and will cmd timeout as seen. -- You are receiving this mail because: You are the assignee for the bug.
