[Bug 1530557] Re: Random hard freezes under X on a laptop with Intel BayTrail processor (ASUS R752MA), Ubuntu 15.10
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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thomas Moestl, thank you for reporting this and helping make Ubuntu better.

Thomas Moestl, to clarify, did this issue not occur in a release prior to 15.10? ** Description changed: 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 opened and being worked in under Unity. The MagicSysReq keys are not functional any more once the hang has occurred, there is no information in the logs, and no crash dump can be obtained by using the soft or nmi watchdogs, panic_on_oops etc. - The BIOS was updated to the latest version available from ASUS: - I have tried the latest mainline kernel build from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D , linux- image-4.4.0-040400rc7-generic_4.4.0-040400rc7.201512272230_amd64.deb (4.4-rc7), and the hangs still occur under the same circumstances. Some research has led me to https://bugzilla.kernel.org/show_bug.cgi?id=109051 , and I believe that - it describes the exact problem I am experiencing. In particular, the - workaround mentioned in there. adding the intel_idle.max_cstate=1 kernel - option, seems to work for me (and my machine is based on the Intel - BayTrail, as mentioned in that report). + it describes the exact problem I am experiencing. - (I am writing this report with this option with this enabled now, so - don't be surprised to see it in the kernel command line). + WORKAROUND: Use kernel parameter: + intel_idle.max_cstate=1 ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: linux-image-4.2.0-22-generic 4.2.0-22.27 ProcVersionSignature: Ubuntu 4.2.0-22.27-generic 4.2.6 Uname: Linux 4.2.0-22-generic x86_64 ApportVersion: 2.19.1-0ubuntu5 Architecture: amd64 AudioDevicesInUse: - USERPID ACCESS COMMAND - /dev/snd/controlC0: tmm2184 F pulseaudio + USERPID ACCESS COMMAND + /dev/snd/controlC0: tmm2184 F pulseaudio CurrentDesktop: Unity Date: Sat Jan 2 16:56:51 2016 HibernationDevice: RESUME=UUID=f079f6d2-d58a-474c-ae48-d903be124a02 InstallationDate: Installed on 2015-10-21 (72 days ago) InstallationMedia: Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) MachineType: ASUSTeK COMPUTER INC.
