Well no hangs for now! I downloaded the 3.13.2 kernel, applied the patch again and compiled it. From now on I'll start using this instead of the 3.13.1.
The difference I might experience compared to when running without the patch, but I'm not sure at all, if there is a difference it is quite small: during firefox rendering (or something else inside the app) freeze for a fraction of second (like half second or so). During such short and temporary freezes it was, rarely, happening the hang. As I said now there is no GPU hang, dmesg is always 100% clear for drm and i915 stuff, but those micro freezes might be a little more frequent with the patch. Again I want to stress this is very hard to quantify and so feel free to simply ignore this. It might just be part of the fact I'm keeping a lot more attention than usual on rendering times to spot an hang. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1274779 Title: [ivb] hang on pageflip (IPEHR: 0x0a000001) To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1274779/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
