Public bug reported:
I apologise in advance, this is my first report, therefore I am not sure if
everything has been automatically collected, or if I need to provide further
information than a short explanation of the problem.
After updating the kernel at 4.4.0-128 on Ubuntu 16.04, first I had massive
problems with the sound drivers. Then they disappeared (by themselves I would
say, I had many tests but I don't think I screwed up anything serious) and,
instead, now my sistem freezes at login screen. Sometimes it gives me the
message that the wireless has been found. The mouse is available but I cannot
interact with the screen, and also the clock is frozen. I have to brutally
switch off the laptop for rebooting. A further kernel update to 4.4.0-130
didn't help, either.
