Title: [drm] HPD interrupt storm detected on connector DP-1: switching from hotplug detection to polling Status in “xserver-xorg-video-intel” package in Ubuntu: New Bug description: I have a haswell motherboard with 3 1080p monitors connected, 2 directly via HDMI and a 3rd HDMI connected to an active displayport dongle. The monitor on the displayport connection had been working fairly reliably until I decided to finally upgrade my bios to fix some other issues (big mistake, since I late found out its nearly impossible to downgrade). Since I upgraded the monitor nearly never works, I did get it to show display a few times but I'm not sure how that happened. At the moment while researching information to add to this post it actually started working for the moment. When I run xrandr it causes the screens to blink rapidly for around 30sec-1min. In dmesg I see instances of: [ 10.053292] [drm] HPD interrupt storm detected on connector DP-1: switching from hotplug detection to polling [ 240.125029] [drm] HPD interrupt storm detected on connector DP-1: switching from hotplug detection to polling Also fwiw I get different errors, and a kernel backtrace, but still no display on current drm-intel-nightly from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/ And of course it all still works fine under Windows 8.1. Searching google I see other instances of people with the same problem on the i915 driver on other systems like ThinkPad, etc. eg: https://bugzilla.redhat.com/show_bug.cgi?id=1062571 http://comments.gmane.org/gmane.comp.freedesktop.xorg.drivers.intel/23611 And a few possibly unrelated things in fdo bugzilla ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xorg 1:7.7+1ubuntu8 ProcVersionSignature: Ubuntu 3.13.0-34.60-generic 3.13.11.4 Uname: Linux 3.13.0-34-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.14.1-0ubuntu3.3 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None Date: Sat Aug 23 01:14:48 2014 DistUpgraded: Fresh install DistroCodename: trusty DistroVariant: ubuntu ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06) (prog-if 00 [VGA controller]) Subsystem: Gigabyte Technology Co., Ltd Device [1458:d000] InstallationDate: Installed on 2014-03-16 (160 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Alpha amd64 (20140315) MachineType: Gigabyte Technology Co., Ltd.
