Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.3 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

   I began to have problems one or two days ago before I performed an
update today.
The problems were in the form of error notice dialog bubbles that appeared
during normal use.
I spent time yesterday working on spreadsheets, both online (Google) and
locally (LibreOffice).
I don't remember the details.
   Today, I saw the update notice, so I closed Firefox and LibreOffice and
began the update. I came back awhile later and found an error dialog
again. I closed the error dialog but the update was frozen. I should have
taken a screenshot of the update details but did not.
   I tried starting System Monitor and Firefox from the launcher. I got
the little busy symbol while they tried to start but they did not start. I
started Gnucash and closed it. I attempted to restart (via the button at
top right desktop) but that didn't work. I had a terminal window open at
the time and saw the shutting-down broadcast message but it didn't
restart. I selected shutdown but that didn't work either. Finally, I held
the power button down and restarted.
   I was surprised when the restart was successful. I expected to have a
problem because I had a problem months ago with the grub bootloader but
that passed.
   Since the restart, I've worked on LibreOffice sheets and Firefox but not
Google docs. I have experienced error messages and have included two
recent screenshots taken while I've composed this.

I'm willing to assist but be aware I'm not a computer science major. I
need instruction.
