I first noticed the problem on kernel 4.4.0-81. The computer froze up a few times before I started digging into the logs to try and figure out what was wrong. It was freezing about 3-4 times per day.
I rolled back to kernel 4.4.0-79, which seemed to be more stable but still suffered an Oops at least once per day. Upgraded to 4.4.0-83 when it became available, but still suffering an Oops occasionally. Also around this time I was suffering graphics issues where the display became unresponsive. There was no kernel oops, but it seemed the nouveau driver was crashing. I've switched to the nvidia proprietry driver, which has resulted in a stable display, but even since then a kernel oops reoccured. Most recent log of the oops below. I'm probably not too keen to go mainline kernel as this is not a testing system - but could we achieve a similar test if I went for the HWE kernel (which I think is currently 4.8 ?) Thank you for your reply!
