again. This was already the 3rd or 4th freeze of the day.

Title:
System freezes occasionally
Status in linux package in Ubuntu:
Confirmed
Bug description:
Occasionally my system freezes totally. When this happens, the screen
totally freezes, no mouse movements anymore. Switching to Console via
Ctrl-Alt-F1 or rebooting via Ctrl-Alt-Del does not work. I have waited
at least 30 min, but the system doesn't seem to recover.
Some days my system will run for many hours without any problem, and
on other days I experience 2 or 3 freezes in an hour time. So far I
have not noticed any similarities between the moments of freezing in
regard to programs running etc.
I filled in this report after reading
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509723 which
seemed to describe the same thing to me, on a same brand laptop. The
freezes happened both on Ubuntu 15.04 and 15.10
