I have tested Janne's kernel, but am still experiencing the freezes, even though they have become more rare. I have now finally sent a problem report to Len Brown and linux-pm (sorry for the delay, wanted to test Janne's kernel before I did to make sure, and also had to test on 4.4rc8, which has c

The symptoms were slightly different this time (the display turned black, which has happened

The drm.intel team seems to have come to the conclusion that reverting this change does not fix the issue, at least not for everybody, although it might make the hangs much more rare. There exists a drm-intel bug report for this issue with all the details: https://bugs.freedesktop.org/show_bug.c

Hmmm, I don't remember, actually. When I got this machine, I installed from a 14.04 DVD, but immediately updated to 15.10 via 15.04 before I even really started using it. I don't remember it having hung in the few hours I had it run on 14.04 or 15.04 while setting things up, but I could be wrong

Public bug reported: System freezes hard when working under X, sometimes after minutes, sometimes after hours. Usually, but not always, graphics-intensive applications like viewing videos will trigger the hangs after a while, but they can also (much more rarely) occur when e.g. only an xterm is op

I am experiencing this bug as well, on the same hardware. I have tested the mainline builds, and can confirm that the bug exists with linux-image-4.4.0-040400rc7-generic_4.4.0-040400rc7.201512272230_amd64 as well. After some searching, it appears that this bug is known in upstream: https://bugzi
