If this is now fixed in mainline, it might be worth testing the latest upstream stable 4.4 kernel. It can be downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.13-xenial/ If 4.4.13 upstream stable fixes this bug, then the commit will be applied to Xenial through the normal stable update process. However, if it does not fix the bug, the real fix may not have been cc'd to stable. However, it may have been and just not landed yet. The other option if this is not fixed in upstream 4.4 stable, is to perform a "Reverse" bisect to identify the commit that fixes this. ** Also affects: linux (Ubuntu Xenial) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Xenial) Status: New => In Progress ** Changed in: linux (Ubuntu Xenial) Importance: Undecided => High ** Changed in: linux (Ubuntu Xenial) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575467 Title: [Dell Inspiron 3451] WARNING: CPU: 1 PID: 1297 at /build/linux-lts- utopic-vy2yyy/linux-lts- utopic-3.16.0/drivers/gpu/drm/i915/intel_display.c:1743 vlv_wait_port_ready+0x126/0x170 [i915]() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1575467/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
