[Bug 1575467] [NEW] Ubuntu 16.04 consistently freezes up / hangs

 

You have been subscribed to a public bug:

Not sure what package this is related to. My best guess is Unity, but i
honestly have no idea. After upgrading from stock Ubuntu 14.04 to 16.04
on my Dell Inspiron laptop consistently freezes up and is unresponsive
keyboard or mouse. The only way is to do a hard shutdown. I'm usually in
a browser when this happens, and often watching a video or two. So i
wonder if this has something to do with my memory buffer or something.
It seems to happen more often in Google Chrome than Firefox, but it
happens with both. I know Google Chrome uses more memory though. And it
has happened at least once with no videos loaded, so i doubt it's some
sort of weird flash issue. I haven’t observed it freeze / hang when I’m
not in a browser, but that's mainly what i use my laptop for, so that's
where most of my time is spent.

I will try to upload any log files that people think may be useful. I
will see if i can do the recommended ssh monitoring method while trying
to reproduce it to see if i can see an error that way.


Not sure if this hardware info helps:
