Comment 3 for bug 1594046

The suggestion from
http://askubuntu.com/questions/776069/ubuntu-16-04-freezes-during-use
which I found using the search mentioned in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1578944

to add intel_idle.max_cstate=1
to the options on GRUB_CMDLINE_LINUX_DEFAULT=
doesnt seem to have worked.

I applied it to the default grub option, did sudo update-grub, restarted, logged on, did a few things then went away to do some other stuff. When I resumed working on the machine, it had frozen, except for the mouse pointer, which was able to be moved around, but no click or keyboard action got any response from the system.

(the initial suggestion from the ask ubuntu answer referred to above was to replace "quiet splash" with intel_idle.max_cstate=1, but the later comment said just adding it worked for that person, so I tried adding it. I will now try replacing (i.e. removing the "quiet splash" as well as adding the above) instead and see if that works)

meanwhile, one of the items I read mentioned same mouse pointer was able to be controlled but all else frozen. Will search again for that and see if it had another solution which I can try after I check the replace referred to above.
