Description Yan Pas 2016-07-06 14:39:26 UTC

I have USB to serial adapter UC232-A. If I plug it in and leave computer sleeping for several hours (I guess that data is accumulated in buffer), then it will wake up for a long time (minute or two). Also NetworkManager becomes broken after wakeup


lsmod |grep -i ser
