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. I noticed it pretty much immediately once I had 15.10 running, but it was much rarer then and I did not have time to go bug hunting immediately.
If it helps, however, I can confirm that the issue occurs with linux- image-extra-3.19.0-31-generic (version 3.19.0-31.36), as well, which is the latest image that is installed via linux-image-generic-lts-vivid on 15.10. Just as an addendum, the machine is stable when booted into Win 8.1, even under heavy graphics loads such as games, and now is under Ubuntu as well with intel_idle.max_cstate=1 , so I believe that hardware flakiness is unlikely to be the cause (especially since a lot of people are reporting the same issue, amenable to the same workaround, on a variety of different BayTrail-based hardware in the above kernel.org bug report). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1530557 Title: Random hard freezes under X on a laptop with Intel BayTrail processor (ASUS R752MA), Ubuntu 15.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1530557/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
