I found a reference here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1720580 and here: https://lkml.org/lkml/2017/6/12/504

Does this affect anybody else? It happened to me with the stock ubuntu, and also with my build of gentoo.

To me, it happens regularly but not often. Maybe, once every 8 hours or so. It once helped to do

rmmod 8723bs
modprobe 8723bs

No, because on launchpad they say it did not help. Though I can still try :-)

khumarahn commented 6 years ago

I tested the patch, it does not help indeed.
