[arch-general] [Solved] Bluetooth no more working after update

[Peter Nabbefeld]

Today I got an update of extra/glib-networking and after restart my
bluetooth interface seems to be working again - probably some interface
problems between modules caused the problems? However, most important
for me, that I can use bluetooth again. :) :) :)

Kind regards,
Peter
