Hope the information helps, at least somebody else: Exact same issue on Skylake-desktop PCs. Tested on 12 PCs in our pc lab. Getting the trace in boot log on every single one. It appears short after boot, by the time lightdm shows up. All machines run with two displays.
MB/BIOS: MSI MS-7971/Z170-A PRO (MS-7971), BIOS 1.D0 08/30/2016 CPU: i3-6100 So far there are no issues visible except the coredump/trace. We had, however, one machine which lost video signal ~one sec after lightdm showed up. X was still running (since I could login blindly via lightdm). The issue disappeared after we started benchmarking the machine. Can't reproduce anymore. After installing the proposed kernel from canonical-kernel-team ppa the issue seems resolved. Any idea when the patch hits v4.4.0? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1643566 Title: [i915_bpo] Intermittent display outage with external monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1643566/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
